fix(consult): write the answer in the step that saw the chart (BUG-1053)

The natal loop's step after run-jyotish-consultation saw the evidence, but
its text was drained and a second, blind compose stream (history + question
only, empty findings) wrote the user-visible answer. Remove compose,
interpret and the drain; keep the loop's own final-step text.

- stepScopedAnswer: per-step holding; text of a step that calls a tool is
  dropped, so narration around tool calls never reaches the answer
- writing shape (opener + four headings) moves into the user turn
- length continuation receives the calculation result; Pass 4 whole-answer
  reject retries through retryForAnswer with the rewrite hint
- createConsultationRunClock: tools keep the 110s tool phase; the loop is
  handed to the 70s answer clock when the calculation result arrives
- settlement judges the step that wrote the answer (BUG-1051 kept)

+## 普通咨询一遍成文（2026-09-27，BUG-1053）

+本命咨询不再有单独的「写结论」阶段：算完盘后，同一个模型循环接着就写回答。时间线的变化只有两处，没有新组件、没有新动效。一是不再出现「正在整理判断依据」「正在写结论」这两个阶段事件，也不再发 `think.step`；计划里的思考行在第一段正文出现时收口（沿用 `completeLiveThink`），写作行的进行中句统一为「正在组织回答」。二是第一段正文要等模型写出第一个二级标题或满 160 字才出现（为了把工具前后的过程说明挡在正文外），开场句会整段一起到达，之后照常按帧放出。截断、停止、失败三种收口与提示不变（BUG-1051）。

 ## 校正开场与步骤回执（2026-09-26，BUG-1049 / BUG-1050）
 
 开场一轮只有两段字：正文两句讲做法（要把出生时间缩小到更准的范围、现在先在哪段时间里找；你说几件大事和大概年月，我拿去和星盘对照），下面是问题块里的题干（六个例子 + 一个带年月的回答示例）。题干只出现一次：正文里和题干逐句相同或几乎相同的句子才会被去掉；只是开头几个字一样、内容不同的句子保留（以前按前 12 个字判定，把正文里的例子句删掉了）。
