refactor(prompts): unify action schema & optimize trading discipline

## Core Changes

### 1. adaptive.txt - Adopt v5.5.6.1 strict strategy
- Migrate from dual-strategy system to unified adaptive approach
- Maintain strict confidence threshold ≥85 (anti-overtrading)
- Remove complex market state detection, focus on signal quality
- Explicitly disable partial_close (full exit only)
- -160 lines (removed redundant strategy logic)

### 2. nof1.txt - Fix contradictions & align standards
- ✅ Fix: Remove "NO partial exits" contradiction (now explicitly supported)
- ✅ Unify: Change confidence threshold from 60 → 75
- ✅ Unify: Change risk-reward ratio from 2:1 → 3:1
- Add confidence level guidance (75-85: good, 85-100: high)
- +85 lines (enhanced risk management framework)

### 3. default.txt - Add standardized output format
- Add structured thinking summary format
- Add comprehensive JSON schema documentation
- Add required fields rules for all action types
- +36 lines (improved contract clarity)

## Action Schema Migration

All prompts now use unified action naming:
- ✅ open_long / open_short (was: buy_to_enter / sell_to_enter)
- ✅ close_long / close_short (was: close)
- ✅ update_stop_loss / update_take_profit (new)
- ✅ partial_close (new, nof1 only)
- ✅ hold / wait (unchanged)

## Confidence Scale Migration

- ✅ Changed from 0-1 float to 0-100 integer across all prompts
- ✅ Opening threshold: adaptive=85, nof1=75, default=75
- ✅ Prevents overtrading through strict quality control

## Risk-Reward Standardization

- ✅ Minimum RR ratio: 1:3 across all prompts
- ✅ Replaces previous 1:2 requirement in nof1.txt

## Breaking Changes

- Backend must support new action names
- Confidence field now expects integer 0-100 (not float 0-1)
- partial_close action available in nof1.txt only

## Prompt Positioning

- **adaptive.txt**: Strict strategy (conf≥85, RR≥1:3, no partial exits)
- **nof1.txt**: English framework (conf≥75, RR≥1:3, supports partial_close)
- **default.txt**: Balanced CN strategy (conf≥75, RR≥1:3)

 # ACTION SPACE DEFINITION
 
-You have exactly FOUR possible actions per decision cycle:
+You can issue the following actions each decision cycle:
 
-1. **buy_to_enter**: Open a new LONG position (bet on price appreciation)
-   - Use when: Bullish technical setup, positive momentum, risk-reward favors upside
+1. **open_long** – Open a new LONG position
+   - Use when: Bullish technical setup、正向动量、风险回报 ≥ 标准
 
-2. **sell_to_enter**: Open a new SHORT position (bet on price depreciation)
-   - Use when: Bearish technical setup, negative momentum, risk-reward favors downside
+2. **open_short** – Open a new SHORT position
+   - Use when: Bearish technical setup、负向动量、风险回报 ≥ 标准
 
-3. **hold**: Maintain current positions without modification
-   - Use when: Existing positions are performing as expected, or no clear edge exists
+3. **close_long / close_short** – Close an existing position（多头或空头）
+   - Use when: Profit target reached、stop-loss triggered、invalidated thesis
 
-4. **close**: Exit an existing position entirely
-   - Use when: Profit target reached, stop loss triggered, or thesis invalidated
+4. **update_stop_loss** – Adjust stop-loss price for the active position
+5. **update_take_profit** – Adjust take-profit price for the active position
+6. **partial_close** – Close part of the current position（需要指定百分比）
+
+7. **hold** – Maintain the current position without modification
+   - Use when: Position thesis remains valid、无更佳操作
+
+8. **wait** – Stay flat（不持仓）
+   - Use when: 没有明确信号、冷却期、资金不足或信心不足
 
 ## Position Management Constraints
 
 - **NO pyramiding**: Cannot add to existing positions (one position per coin maximum)
 - **NO hedging**: Cannot hold both long and short positions in the same asset
-- **NO partial exits**: Must close entire position at once
+- **Partial exits supported**: Can close positions partially using partial_close action
