fix(rectification): plain-word opening with examples in the stem, plain de-duplicated step receipt (BUG-1049, BUG-1050)

- BUG-1049 (recurrence of BUG-504): the opening stem carries six examples and
  an example answer again and is server-owned on the zero-evidence opening;
  the body is two plain sentences (no 大运/盘面/代表分钟/精确到秒, no year, no
  question). Stem de-dup compares whole sentences / near-equality instead of a
  12-char prefix, which had deleted the body's examples sentence since
  aa7ccb30 (BUG-604) + dd8f35f7 (BUG-648).
- BUG-1050: plain step labels; a finished step label shows once and
  「已完成 N 步」counts shown rows; failed rows read 「…未完成」 from the
  in-progress wording.
- Skill 10.0.30 -> 10.0.31 (OpeningPolicy); 10.0.30 kept as deprecated.
- VOICE / DESIGN / CHANGELOG / BUG_HISTORY / PROGRESS / real-device checklist
  and screenshots.
