fix(rectification): keep spoken collect from silencing the agent

Collect focus was leaking discriminator probes into the agent prompt and
inheriting choice identity. Mark spoken questions, hide current_probe
unless a real choice card exists, strip fallback identity, log persist
failures, and align the decision probe with the plan including birthDate.

 - 用户现象：点选两道区分题后，助手口述家人采集问但没有选项卡。用户用自由文本回答后，服务端回没有出路的终结话术；`current_question` 与 `choice_card` 均为 null，case 停在 `collecting_evidence`；该回合 receipt 的 phases / tools / tool_activities 全空，用户这句话里的新证据没有入账本。
 - 触发条件：训练证据已齐、已答 dasha 边界探针、剩余探针含无年份 varga 与缺 `style_options` 的 `varga_style`；方法覆盖未齐时出题层回落到口述采集；随后用户在无 active choice focus 时发自由文本。
 - 根因：`inspectDiscriminatorProbes` 用 `withCompletedContrastOptions` 把缺 `style_options` 的 `varga_style` 降级后仍视为可渲染，并选出无年份 varga 探针进入 `ask_candidate_discriminator`。`renderableContrastProbe` 仍走未降级的 `completeStyleOptions`，把同一探针静默丢弃。无年份桶只在覆盖齐时使用，于是回落到 `source=method_coverage` 的家人采集且不带 `choice_frame`。路由只信决策层：`persistServerOwnedFocus` skipped、`openQuestionFromPersistedFocus` 为 null 后直接返回终结话术，既不落证据也不跑 Agent。口述采集题不落 focus，刷新后问题丢失；卡片持久化失败时返回无正文下一步。
-- 修复：出题层与决策层共用 `withCompletedContrastOptions`；丢弃探针写入 `dropped_probes`。仅当出题层给出 `intent=distinguish_candidates` 且带 `choice_frame` 的 followup 时才进入 `ask_candidate_discriminator`，否则落到采集。消息分支拿不到可渲染卡且仍有 followup 时落入 `runV9AgentTurn`；仅当 `next_followup` 为 null 时才收口，话术给出继续采集或按区间看盘。口述采集持久化不带 choice 的 collect focus；卡片持久化失败时落到口述采集下一步。冲突探针写回时保留 `style_options`。Skill 版本保持 `10.0.13`。未放宽 confirmation gate，未增加「已确认唯一分钟」路径。
-- 验证：`frontend/tests/rectification-discriminator-followup-consistency.test.ts` 锁定同一探针池上决策层与出题层一致、缺 `style_options` 的 D9/D10 风格题在方法覆盖未齐时仍出区分卡、无星座时钟键 fail-closed 到采集、消息路径不再返回死路话术。`rectification-answer-choice.test.ts` 锁定口述采集后仍有 collect focus 与 `current_question`。`rectification-server-focus.test.ts` 锁定 collect schema 不是未渲染区分卡。`rectification-turn-intent-classifier.test.ts` 按新收口话术改断言。`npx tsc --noEmit` 与 `npx tsx --test tests/*.test.ts`。
-- 防复发：可渲染判定必须共用选项补全，不得一边降级接受一边静默丢弃。无卡时不得把用户消息当终结话术丢掉。有合法 choice schema 的 active focus 仍走轻量分类 + `applyRectificationChoice`。不得引入语义正则、A/B/C/D 位置推断或静态选项 fallback。
