fix: mention 重复投递 + mail 失败通知竞态保护 + §14 设计文档同步
Bug 1: spawn_full_agent use_main_session 返回 None 导致 mention 重复投递 - 根因: use_main_session=True 时 session_id=None, return None 被 ticker _process_posts 误判为 spawn 失败, 每次 tick 都重试 - 修复: 引入 effective_sid = session_id or 'main', 统一用于 _register_session / _monitor_process / return value Bug 2: _mark_task failed 时未检查已完成状态导致误发投递失败通知 - 根因: spawner 标 failed 和 handler 标 done 竞态条件下, 已完成的 mail task 被误发投递失败通知 - 修复: notify_mail_failed 调用前加防御性检查, 若 task 已 done 则跳过 设计文档: §13 三个 handler sections 列表同步 DeliveryChecklistSection 及 GiteaConventionSection / WikiGuideSection, 更新 section 复用分析表 及文件结构 section 计数

## 共性 Section(三 handler 共享)
|
||||
|
||||
以下三个 Section 在 `prompt_composer.py` 中统一定义,被 Task/Mail/Toolchain 三个 handler 共同注入:

|
||||
| Section | priority | 用途 |
|
||||

| `GiteaConventionSection` | 55 | Gitea Issue/PR 标题规范、分支命名、提交格式 |

|
||||
| `WikiGuideSection` | 60 | Wiki 知识库检索指引(检索路径、优先级、知识缺口记录) |
|
||||
|
||||
设计意图:将跨 handler 的共性约束从各 handler 的 ConstraintsSection 中抽离,避免重复维护。
