元自成长层：meta_growth 每周扫描修复模式→自动扩展扫描规则
- scripts/meta_growth.py (NEW): 每周日22:00分析git log中的修复模式， 识别新问题类型，向 hardcode_scanner 注入新规则 - scripts/hardcode_scanner.py (MODIFIED): 预置扩展点注释， meta_growth 可直接在其后追加新规则元组 - docs/SELF_GROWTH_SYSTEM.md (UPDATED): 新增第七章"元自成长层" - cron: 元自成长-每周 周日22:00 no_agent 设计理念：自成长机制本身必须也是自成长的。 hardcode_scanner 能扫什么不是写死的——meta_growth 会从你的修复习惯中学习新的扫描类别。
