Subject: tasks: 任务清单纳入 git 版本管理（固定文件+自动提交+非破坏式恢复）
X-Git-Url: http://acesimba.cloud/gitweb/?a=commitdiff_plain;h=e361c50afd231f2c9afac32e09babc454dd571ae;p=codebuddy-web.git

tasks: 任务清单纳入 git 版本管理（固定文件+自动提交+非破坏式恢复）

- .gitignore: 取消忽略 data/tasks.json，忽略其 .tmp/损坏备份
- app.py: save_tasks 保存后自动 git commit；load_tasks 缺失/损坏时优先从 git HEAD 恢复，不再静默用单任务种子覆盖
