## Problem
GetCurrentKlines had two critical bugs causing price data to become stale:
1. Incorrect return logic: returned error even when data fetch succeeded
2. Race condition: returned slice reference instead of deep copy, causing concurrent data corruption
## Impact
- BTC price stuck at 106xxx while actual market price was 107xxx+
- LLM calculated take-profit based on stale prices → orders failed validation
- Statistics showed incorrect P&L (0.00%) due to corrupted historical data
- Alt-coins filtered out due to failed market data fetch
## Solution
1. Fixed return logic: only return error when actual failure occurs
2. Return deep copy instead of reference to prevent race conditions
3. Downgrade subscription errors to warnings (non-blocking)
## Test Results
✅ Price updates in real-time
✅ Take-profit orders execute successfully
✅ P&L calculations accurate
✅ Alt-coins now tradeable

Fixed critical bug where 4h kline data was incorrectly stored with
3m kline data, causing data mismatch.
Changes:
- Changed `m.klineDataMap4h.Store(s, klines)` to `klines4h`
- Updated log message to use `len(klines4h)` instead of `len(klines)`
This bug would cause 4h kline queries to return 3m data, leading to
incorrect technical indicator calculations.

- market/ai_signal.go
- market/market_data.go
- scanner/ai_scanner.go
Keep only market/data.go to align with internal version structure.

Problem: When TotalTrades == 0 (no completed trades), formatPerformanceFeedback
would return early, hiding Sharpe ratio and adaptive behavior recommendations
from AI's prompt. This caused AI to say "no historical data" even though Sharpe
ratio was calculated and displayed on frontend.
Solution:
- Display Sharpe ratio BEFORE checking TotalTrades
- Don't return early when TotalTrades == 0
- Always show adaptive behavior recommendations if Sharpe ratio exists
- Sharpe ratio is calculated from account equity changes, not just closed trades
Impact: AI can now properly use Sharpe ratio for self-evolution, even in early
stages before any trades are closed.
