Fix: F3 tool details toggle, sidebar width, and sync docs with code

- Fix F3 tool details: use display:none/block instead of re-compose
- Increase sidebar width from 40 to 70 for readability
- Sync 一键启动指南.md with actual entry points (trulymem_entry.py)
- Rewrite 工作记忆链机制说明.md with actual task_* tool APIs
- Rewrite 架构.md with actual file structure (38 Python files)
- Update docs/README.md with complete feature list
