feedback7: merge fb7-gh-sim — PR #348 (take-the-highest chains), PR #293 (REA-Y in the engine), #329 ports (异客 13 tiles, 歌蕾蒂娅 net radius 1, 搅拌机 latest first, 大帝 uncapped), PR #365 (骨刺 forms + PRTS targeting), #298 (instant non-attack skills recast at most once per attack interval, attacks untouched), #364 (先兆者 shell 3×3), #220 (速射手 air first), 余 skips noStack bonds (owner)

- Conflict: docs/PLAYING.md 技能自动释放 bullet — both insertions kept (the 铁钳号 rule from fb7-owner-sim, the #298
  pacing sentence).
- Grok review: MERGE AFTER FIXES — the HIGH #298 finding (the cast replaced the due attack) fixed on the branch
  (db29acf9: per-skill nextCastAt; golden of #298 alone shrank from 84 scenarios to 2).
- Golden union: 4 matches differ from HEAD though the branch alone left them (coop2-NORMAL-3, coop4-ABYSS-7,
  coop2-NORMAL-8-serverrun, solo-HARD-9-boosted): HEAD's side had moved all four (#333's shop RNG …) and on those new
  bot paths the merged rules apply — the diffs are in-battle layer gains / damage (卡西米尔 50 → 45, 精准 80 → 76,
  叙拉古 176 → 168, kills ±2, solo-HARD-9 LP 397 → 399), no outcome change.
- Broad node --test 5571 (5570 pass, 0 fail, 1 skipped); lint 0 errors; typecheck.
