feat(agent): L2/L4 记忆注入——项目规范 + 全局规范文件喂进 4 处 prompt

- L2 projects.agent_rules 列（schema+迁移+类型+mapper+patchProject+API 透传）
- L4 protocol.readGlobalAgentRules()：worker 直接读 <data>/agent-global.md（非DB，
  不读用户 ~/.claude/CLAUDE.md，避免个人习惯与受控执行冲突）
- runner.rulesHeaderLines 注入 executor/planner/conflict；reviewer 同注入
- 顺序：全局规范(L4)→项目规范(L2)→任务内容→上次失败(L1)→执行约束
