feat(agent): 接通 plan 自动放行（autoApprovePlan）+ 项目配置可写

之前 auto_approve_plan/auto_approve_exec/checks 列与 Project 类型已存在，但
PatchProjectInput 不含它们 → 无法启用（dead config）。本次接通：
- PatchProjectInput + patchProject 支持 autoApprovePlan/autoApproveExec/checks
- API PATCH /projects 透传三字段
- ingest decompose-result：auto-approved + autoApprovePlan + 全 easy + 子任务≤5
  → store.decide(accept) 跳过 plan_review 直达 decomposed（默认关）
