fix(rectification): align leftover prompt and focus tests with the shrunk agent contract

Independent Staging Quality Gate 2141 failed because four tests still matched the old Mastra prompt wall and treated an unrenderable focus as null.

 - 触发条件：varga 风格标签含禁词或不足两项；已持久化 Focus 的 choice schema 缺四选项；`proposeAllowed` 为 false 时模型仍看到 `offer-candidates`。
 - 根因：选项补全和可渲染检查只返回成功数组或 `null`，没有 `reason`。读路径把坏 schema 当成「没有题」。Agent 工具表不看 `decideFromDossier`。TS/Python 合同没有 byte-equal golden。`uniquify` 曾用 `answer_class` 当可见后缀。
 - 修复：补全/可渲染返回 `{ ok, options|reason }`。`inspectDiscriminatorProbes` 把丢题写入 `decision.droppedProbes` 和 receipt `dropped_probes`。GET/`turn_decision` 对坏选择题返回 `{ unrenderable: true, reason }`，采集类 Focus 仍为 `null`。`createRectificationV9AgentTools(ctx, decision)` 按 phase / `proposeAllowed` / `selectionAllowed` / `canConfirmExactMinute` 过滤工具。合同 golden 在 `contracts/probe-question-v1.json`，引擎 client 拒不匹配的 `question_contract_version`。重复标签用 `·2` 而不是 `weak_yes`。Mastra 提示词删掉已由代码执行的外貌/财务/工具禁令，Skill 保持 10.0.13。`lib/birth-time-*` 仍被 `app/` 与 `components/` 的 guided/journey/intake 与 `/api/birth-time-journey`、`/api/birth-time-guide` 引用，本批不删。

 - 防复发：不得把 `completeStyleOptions` / `isRenderableProbe` 改回只返回数组或 boolean。不得把坏选择题投影成 `current_question: null`。不得在无决策时按 phase 过滤工具后，再把 `offer-candidates` 写进提示词禁令。不得用 `answer_class` 当可见标签后缀。不得在本路径删除仍被 journey/guide UI 引用的 `birth-time-*`。不得把 Skill 升出版本。
