chore: simplify PR template (OpenClaw-style)

The pr-template-suggester workflow was triggered on opened/edited/synchronize
events and forcefully replaced the PR body with a template when body < 100 chars.
This caused user-written descriptions to be overwritten.

Replace with a lightweight labeler (OpenClaw-style) that:
- Only adds labels (backend/frontend/docs, size: XS/S/M/L/XL)
- Never modifies the PR body
- Simplified unified PR template at .github/pull_request_template.md

+# BlockRun Base (EVM) Wallet Setup Guide
+
+This guide explains how to use a Base network EVM wallet to pay for AI usage through BlockRun — no API key required.
+
+**Language:** [English](blockrun-base-wallet.md) | [中文](blockrun-base-wallet.zh-CN.md)
+
+## What is BlockRun?
+
+[BlockRun](https://blockrun.ai) is a decentralized AI inference gateway that lets you access top AI models (Claude, GPT, Gemini, Grok, DeepSeek, etc.) by paying per request with USDC — no monthly subscriptions, no API key signups.
+
+NOFX integrates BlockRun via the **x402 micropayment protocol**: each AI inference request automatically pays a small USDC fee directly from your wallet. You only pay for what you use.
+
+## Why Use BlockRun?
+
+| Feature | Traditional API Key | BlockRun Wallet |
+|---------|-------------------|-----------------|
+| Setup | Register + billing | Just a wallet address |
+| Cost model | Monthly subscription | Pay-per-request |
+| Models | One provider | All top models |
+| Privacy | Account required | Pseudonymous |
+| Control | Rate limits apply | Your wallet, your budget |
+
+## Prerequisites
+
+- An EVM wallet with USDC on **Base network** (chain ID 8453)
+- The wallet private key (hex format: `0x...`)
+
+### Getting USDC on Base
+
+1. Buy USDC on Coinbase and withdraw to Base, **or**
+2. Bridge USDC from Ethereum using [bridge.base.org](https://bridge.base.org), **or**
+3. Swap on [Aerodrome](https://aerodrome.finance) or [Uniswap](https://app.uniswap.org) on Base
+
+> **Tip:** A few dollars of USDC is enough to start — each AI call costs fractions of a cent.
+
+## Step 1: Get Your Wallet Private Key
+
+> ⚠️ **Security Warning:** Never share your private key with anyone. Use a dedicated trading wallet, not your main holdings wallet.
+
+**Option A — Create a new wallet (recommended):**
+1. Open MetaMask → Create New Account
+2. Go to Account Details → Export Private Key
+3. Copy the hex key (starts with `0x`)
+
+**Option B — Use an existing wallet:**
+1. MetaMask → Account Details → Export Private Key
+2. Enter your MetaMask password to reveal the key
+
+**Option C — Generate via CLI:**
+```bash
+# Using cast (foundry)
+cast wallet new
+# Output: Address: 0x... | Private key: 0x...
+```
+
+## Step 2: Fund the Wallet with USDC on Base
+
+Send USDC to your wallet address on Base network:
+- **USDC contract:** `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`
+- **Network:** Base (chain ID 8453)
+- **Recommended starting amount:** $5–$20 USDC
+
+Check your balance at [basescan.org](https://basescan.org).
+
+## Step 3: Configure in NOFX
+
+1. Open NOFX at `http://localhost:3000`
+2. Log in and go to **Config** tab
+3. Click **+ Add AI Model**
+4. In Step 0, scroll to **Via BlockRun Wallet** section
+5. Select **BlockRun · Base Wallet**
+6. In Step 1, configure:
+   - **Wallet Private Key:** Your hex private key (`0x...`)
+   - **Select Model:** Choose from Claude Opus, GPT-5.4, Gemini 3 Pro, Grok 3, DeepSeek R1, or leave as **Auto** for best available
+7. Click **Save**
+
+## How Payment Works
+
+When NOFX sends an AI request:
+
+1. Request goes to `https://blockrun.ai/api/v1/chat/completions`
+2. Server responds with HTTP `402 Payment Required` + payment details
+3. NOFX signs a **ERC-3009 TransferWithAuthorization** (EIP-712) with your private key
+4. Payment signature is attached and request is retried
+5. BlockRun verifies the signature, routes the request to the AI model, and charges USDC
+
+> **Privacy:** Your private key never leaves your NOFX instance. Only the cryptographic signature is sent.
+
+## Available Models via BlockRun
+
+| Model ID | Provider | Use Case |
+|----------|----------|----------|
+| `gpt-5.4` | OpenAI | Flagship (default) |
+| `claude-opus-4.6` | Anthropic | Flagship |
+| `gemini-3.1-pro` | Google | Flagship |
+| `grok-3` | xAI | Flagship |
+| `deepseek-chat` | DeepSeek | Flagship |
+| `minimax-m2.5` | MiniMax | Flagship |
+
+## Security Best Practices
+
+- ✅ Use a **dedicated wallet** with only trading budget, not your main wallet
+- ✅ Keep only a small USDC balance (top up as needed)
+- ✅ Your private key is encrypted at rest in NOFX's database
+- ✅ Signatures are spend-limited — each signature authorizes only the exact amount for one request
+- ❌ Never export or share your private key outside of NOFX
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| `no private key set` | Check your key was saved correctly; re-enter in Config |
+| `payment retry failed` | Ensure you have USDC on **Base** (not Ethereum mainnet) |
+| `invalid private key` | Key must be hex format with `0x` prefix, 66 chars total |
+| Payment deducted but no response | Check BlockRun status at [blockrun.ai](https://blockrun.ai) |
+| Slow responses | Try selecting a specific model instead of "Auto" |
+
+## Monitoring Spend
+
+Check your USDC balance and transaction history at:
+- [Basescan](https://basescan.org) — search your wallet address
+- [BlockRun dashboard](https://blockrun.ai) — usage history

+# BlockRun Solana Wallet Setup Guide
+
+This guide explains how to use a Solana wallet to pay for AI usage through BlockRun — no API key required.
+
+**Language:** [English](blockrun-sol-wallet.md) | [中文](blockrun-sol-wallet.zh-CN.md)
+
+## What is BlockRun?
+
+[BlockRun](https://blockrun.ai) is a decentralized AI inference gateway that lets you access top AI models (Claude, GPT, Gemini, Grok, DeepSeek, etc.) by paying per request with USDC — no monthly subscriptions, no API key signups.
+
+NOFX integrates BlockRun via the **x402 micropayment protocol** on Solana: each AI inference request automatically pays a small USDC fee directly from your wallet.
+
+## Prerequisites
+
+- A Solana wallet with USDC on **Solana mainnet**
+- The wallet private key (base58-encoded, 64 bytes — standard Solana keypair format)
+
+### Getting USDC on Solana
+
+1. Buy SOL on any exchange and withdraw to your Solana wallet, then swap to USDC on [Jupiter](https://jup.ag), **or**
+2. Buy USDC directly on an exchange and withdraw to Solana, **or**
+3. Bridge from other chains using [Wormhole](https://wormhole.com)
+
+> **Tip:** A few dollars of USDC is plenty to start.
+
+## Step 1: Export Your Solana Private Key
+
+> ⚠️ **Security Warning:** Use a dedicated wallet for NOFX — not your main holdings wallet.
+
+**From Phantom Wallet:**
+1. Open Phantom → Settings (gear icon)
+2. Security & Privacy → Export Private Key
+3. Enter your password
+4. Copy the base58 key (looks like: `5J...` — a long string of ~88 characters)
+
+**From Solflare:**
+1. Settings → Export Private Key
+2. The key is displayed in base58 format
+
+**From CLI (solana-keygen):**
+```bash
+# View existing keypair
+cat ~/.config/solana/id.json
+# This is a JSON array — convert to base58 using:
+solana-keygen pubkey ~/.config/solana/id.json
+```
+
+> **Note:** NOFX accepts the **base58-encoded 64-byte keypair** (as exported by Phantom/Solflare). This is the standard format for Solana private keys.
+
+## Step 2: Fund the Wallet with USDC on Solana
+
+Send USDC to your Solana wallet:
+- **USDC SPL token mint:** `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`
+- **Network:** Solana Mainnet
+- **Recommended starting amount:** $5–$20 USDC
+
+Check your balance at [solscan.io](https://solscan.io) or in your wallet app.
+
+## Step 3: Configure in NOFX
+
+1. Open NOFX at `http://localhost:3000`
+2. Log in and go to **Config** tab
+3. Click **+ Add AI Model**
+4. In Step 0, scroll to **Via BlockRun Wallet** section
+5. Select **BlockRun · Solana Wallet**
+6. In Step 1, configure:
+   - **Wallet Private Key:** Your base58-encoded Solana private key
+   - **Select Model:** Choose from Claude Opus, GPT-5.4, Gemini 3 Pro, Grok 3, DeepSeek R1, or leave as **Auto** for best available
+7. Click **Save**
+
+## How Payment Works
+
+When NOFX sends an AI request:
+
+1. Request goes to `https://sol.blockrun.ai/api/v1/chat/completions`
+2. Server responds with HTTP `402 Payment Required` + payment details (nonce, recipient, amount)
+3. NOFX signs the payment message `blockrun-payment:{nonce}:{recipient}:{amount}` with your **Ed25519** private key
+4. Payment signature is attached and request is retried
+5. BlockRun verifies the Ed25519 signature on-chain and routes to the AI model
+
+> **Privacy:** Your private key never leaves your NOFX instance. Only the cryptographic signature is sent.
+
+## Available Models via BlockRun
+
+| Model ID | Provider | Use Case |
+|----------|----------|----------|
+| `gpt-5.4` | OpenAI | Flagship (default) |
+| `claude-opus-4.6` | Anthropic | Flagship |
+| `gemini-3.1-pro` | Google | Flagship |
+| `grok-3` | xAI | Flagship |
+| `deepseek-chat` | DeepSeek | Flagship |
+| `minimax-m2.5` | MiniMax | Flagship |
+
+## Security Best Practices
+
+- ✅ Use a **dedicated trading wallet** with only your AI budget
+- ✅ Keep only a small USDC balance (top up as needed)
+- ✅ Your private key is AES-256 encrypted at rest in NOFX's database
+- ✅ Ed25519 signatures are one-time — each authorizes only one specific payment
+- ❌ Never use your main SOL holdings wallet as the NOFX trading wallet
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| `unexpected key length` | Ensure you exported the full 64-byte keypair (not just the 32-byte seed) |
+| `failed to decode base58` | Key must be base58 encoded (standard Phantom/Solflare export format) |
+| `payment retry failed` | Ensure you have USDC on **Solana mainnet** (not devnet) |
+| No response from server | Check `sol.blockrun.ai` is reachable from your server |
+| Slow responses | Try selecting a specific model instead of "Auto" |
+
+## Monitoring Spend
+
+Check your USDC balance and transaction history at:
+- [Solscan](https://solscan.io) — search your wallet address, filter by USDC token
+- [BlockRun dashboard](https://blockrun.ai) — usage history

+## Your Identity
+- You are operating as: %s
+- Internal user ID (for API calls only): %s
+- When asked "which user / account / email" — answer with the email address above
+- All API calls are made on behalf of this user
+
+## Tool: api_request
+Use the api_request tool to call the NOFX REST API:
+- method: "GET" | "POST" | "PUT" | "DELETE"
+- path: API path; query params go in the path: /api/positions?trader_id=xxx
+- body: JSON object (use {} for GET requests)
+
+## NOFX API Documentation
+
+%s
+
+## CRITICAL: Exact ID Rule (read this before every API call)
+API fields like "ai_model_id", "exchange_id", "strategy_id", "trader_id" require the EXACT "id" value
+from the corresponding API response. NEVER use "provider", "type", or any other field as a substitute.
+
+Wrong:  {"ai_model_id": "deepseek"}          ← "deepseek" is the provider, NOT the id
+Correct: {"ai_model_id": "abc123_deepseek"}  ← full "id" from GET /api/models
+
+The Account State block at the start of this conversation lists every resource with its exact id.
+Read the id field from there and copy it verbatim — do not abbreviate, shorten, or guess.
+
+## Behavior Rules
+1. Reply in the same language the user used (中文→中文, English→English)
+2. Keep final replies concise — show results, not process
+3. Ask for ALL missing required info in ONE message — never ask one field at a time
+4. When user provides enough info, act immediately — no confirmation needed
+5. Be decisive — infer intent from context, use schema to fill in smart defaults
+
+## Verification Rule (CRITICAL)
+After ANY PUT or POST that creates or modifies a resource:
+1. Immediately GET the resource to read actual saved values
+2. Show the user the KEY fields they care about from the GET response
+3. NEVER just say "updated successfully" without showing the actual values
+4. If saved values look wrong, correct them automatically
+
+## Error Handling
+- 400: explain what was wrong, ask user to correct
+- 404: resource doesn't exist — you may have used the wrong ID format; check the Account State for the exact id
+- "AI model not enabled": tell user to enable the model first via PUT /api/models
+- "Exchange not enabled": tell user to enable the exchange first
+- 5xx: server error, ask user to try again
+
+## Account State (injected at conversation start)
+At the start of each new conversation, a [Current Account State] block is provided with:
+- AI Models: all configured models with their IDs and enabled status
+- Exchanges: all configured exchanges with their IDs and enabled status
+- Strategies: all existing strategies with their IDs
+- Traders: all existing traders with their IDs and running status
+
+Use this to:
+- NEVER ask for exchange/model info that is already configured — use the existing IDs directly
+- Know instantly if the user has 0 or N resources of each type
+- If only one exchange/model exists and user doesn't specify, use it directly without asking
+- If multiple exist, list them and ask which one to use
+
+## Common Workflows
+
+**Create strategy** (independent from traders):
+- Never GET trader info just to create a strategy.
+- POST {"name":"<descriptive name>"} — config is OPTIONAL. Backend applies complete working defaults automatically (ai500 top coins, all indicators, standard risk control). Strategy is immediately usable.
+- Only include "config" when user explicitly requests custom settings (specific coins, custom leverage, different timeframes).
+- After POST: GET /api/strategies/:id to verify → show user: name, coin_source.source_type, key risk_control values
+
+**"帮我配置策略并跑起来" / "create strategy and start" (full setup workflow)**:
+Execute these steps IN ORDER with NO user confirmation between them:
+1. POST /api/strategies — body: {"name":"<descriptive name>"} — no config needed, defaults are complete
+2. GET /api/strategies/:id — verify strategy was saved
+3. POST /api/traders — create trader: use exchange_id and model_id from Account State (if only one each, use directly); set strategy_id from step 1; set name matching the strategy
+4. POST /api/traders/:id/start — start the trader
+5. Final reply: show strategy name, trader name, coin source, confirm running
+
+**Update strategy config**:
+1. GET /api/strategies/:id to read current full config
+2. Modify only what user asked (keep all other fields)
+3. PUT /api/strategies/:id with complete merged config
+4. GET /api/strategies/:id to verify → show user actual saved values for changed fields
+
+**Start/stop existing trader**: From Account State, if only one trader, act directly. If multiple, list and ask.
+
+**Query data**: Use trader_id from Account State, then query /api/positions?trader_id=xxx or /api/account?trader_id=xxx etc.`, userEmail, userID, apiDocs)
