fix(release): finish retirement and repair stale CI contracts

[huangruiteng]

The complete release suite exposed an unsupported Todo-event constant left behind by #5054, stale assumptions about the already-capped RPC response, and a missing Decision Context module in both code maps. This removes the unused declaration/facade entry and repairs the existing test/docs contracts.

Production changes delete nine lines only. File/SQLite oversized responses remain ambiguous after dispatch; the same test still verifies complete bounded paging, unchanged authority revisions and shared runtime survival. All original byte/time/module budgets remain unchanged.

Validation: 47 architecture, retired-source, canonical-status, real File/SQLite RPC and bilingual code-map checks pass; Ruff and diff checks pass. The identical real CLI/HTTP fixture at base and reviewed head preserves healthy, refused, independent and recovered Goal observations. Future-facing cleanup removes dead compatibility without a new abstraction; UI/Lark inputs and configuration are unchanged.

动机

#5054 退休旧 Todo event 实现后，status facade 仍保留无消费与公开契约的旧常量，完整主干测试因此失败。本 PR 完成同一退休边界的清理。

改动思路

按既有兼容导出审计规则删除无证据的遗留出口，保留 canonical status collector、typed 旧源拒绝与恢复路径。同时将真实 RPC 测试对齐已有超大响应关闭连接的类型化合同，并补齐中英文模块目录；所有原预算保持。

具体改动

生产代码两个文件共删9行，删除旧常量定义、status import、兼容 allowlist entry，并收紧相邻空行。另补中英文 freshness 模块目录及真实 File／SQLite RPC 断言：超大响应按已有合同返回 EffectRuntimeResponseAmbiguous，继续验证分页完整性、原字节上限与 runtime PID 不变。

关键代码讲解

STATE_EVENT_LOG_BASENAME 已无 repository/doc consumer，定义和 import 同时移除。_PUBLIC_COMPAT_REEXPORTS 只去掉这一项，其余出口仍由完整 identity／consumer 审计保护。CLI/status JSON、native provider、quota、指引与权限没有改变；旧的无支持 Python import 名称明确退休。

原主干失败已复现；修复代码的 architecture／retired-source／canonical-status 共47项通过，Ruff 与 diff hygiene 通过。精确 base/head 用同一真实 CLI／HTTP fixture 验证 healthy、refused、independent 与 recovered Goal，归一化观察完全一致。

对主干的风险

未知外部代码若依赖这一个已退休、无支持契约的 Python 名称会失败，属于 #5054 已声明退休范围；不能凭假想消费保留死兼容。受支持状态与恢复的真实入口保持一致，没有新 state rule、默认开关、guidance／obligation、domain-specific wording 或 authority。UI／Lark 的状态输入不变，不需要新配置入口。最终版本全量资格仍单独执行。

我的整体评价

无阻塞发现，改动直接对应现有 CI 失败。未来改动便利性检查已删除旧兼容 seam，复用现有审计与 read model，无需额外抽象。属于已授权 #5054 自修复的必要后续清理，可在精确 head readiness 通过后合入。

English verdict: APPROVE - 48dbe2d;47focused tests,Ruff and actual base/head CLI/HTTP parity pass;remove only the unsupported retired Todo-event facade name.
