Merge pull request 'Add bounded evidence to work checkpoint candidates' (#31) from feature/fast-slow-u2-u3 into main

Why: the adoption PR is reviewed and its candidate HEAD passed CI; the card closure is folded into the PR so no separate close PR is needed.
Evidence: CI GATE on 18f617d4e8cd63d172a5ab9519271831beb546db; independent Review REPLAY (cursor-agent-stable --mode ask 全新只读会话（fresh_session=true，session id not-observable；codex/pi 因 Token Plan 429 不可用）VERDICT: APPROVE，无阻塞项).
Impact: task card only (moved to .task/archive/).

+## 目标与非目标
+
+目标（Phase 6 十步）：固定 Guidelines SHA（deps/development-guidelines @ 2688fd2be6a52c0bf110e7e6366b6f291ab5e4eb）；增加 AGENT-EXECUTION.md；增加共享执行器薄入口（deps/development-manager @ 42e675fec8e0069646319fcd298e61d03d8cbfd5 + scripts/dm、scripts/agent-exec、scripts/task）；四条路由（implementation/repair/test/review）；任务卡模板与分支元数据；CI 中启用 schema 校验（.gitea/workflows/governance.yml：agent-exec validate + governance check）；一次正例运行；负例（缺配置、坏收据、越界路径、未知副作用）；独立 Review + CI；采纳状态 active。
+
+非目标：不改业务代码与既有测试；不改分支保护（由用户执行）；不发布 tag。
+
+引导说明：AGENT-EXECUTION.md 由 host 以固定版本治理套件（dm-server governance init @ 42e675fec8e0069646319fcd298e61d03d8cbfd5）生成并作为引导配置提交（执行器运行前必须存在有效配置；沿用 DM 采纳先例）；其余文件由实施单元生成。

+## 结果与验证（完成后填写）
+
+- 结果：治理套件已采纳——Guidelines 与 Development-Manager gitlink 固定、AGENT-EXECUTION.md 四条路由、共享执行器薄入口、pre-commit admit、governance CI；采纳状态 active（随合入生效）。
+- 验证：见下表（命令输出由 /tmp/gov-neg/ev.sh 写入 .task/evidence/governance-adoption/，SELF 除非另注）。
+- 影响与剩余项：不改业务代码；本地启用钩子需由人执行 `git config core.hooksPath scripts/hooks`；将 governance 检查设为分支保护必需项属用户双钥匙事项（命令见 Agent-System-Dev 治理主记录）。
