Add detailed guidance chapter for dynamic TP/SL management and partial close operations.
## Changes
- New chapter: "动态止盈止损与部分平仓指引" (Dynamic TP/SL & Partial Close Guidance)
- Inserted between "可用动作" (Actions) and "决策流程" (Decision Flow) sections
- 4 key guidance points covering:
1. Partial close best practices (use clear percentages like 25%/50%/75%)
2. Reassessing remaining position after partial exit
3. Proper use cases for update_stop_loss / update_take_profit
4. Multi-stage exit strategy requirements
## Benefits
- ✅ Provides concrete operational guidelines for AI decision-making
- ✅ Clarifies when and how to use partial_close effectively
- ✅ Emphasizes remaining position management (prevents "orphan" positions)
- ✅ Aligns with existing backend support for partial_close action
## Background
While adaptive.txt already lists partial_close as an available action,
it lacked detailed operational guidance. This enhancement fills that gap
by providing specific percentages, use cases, and multi-stage exit examples.
Backend (decision/engine.go) already validates partial_close with
close_percentage field, so this is purely a prompt enhancement with
no code changes required.
