Gao Mingfei 644501ae07 fix(config): reload AppConfig when config path or mtime changes (#1239)
* fix(config): reload AppConfig when config path or mtime changes

- Track resolved path + mtime; invalidate cache on change
- Preserve set_app_config() injection behavior
- Add regression tests (test_app_config_reload.py)
- Document behavior in README and backend/CLAUDE.md
