feedback5: merge CB3 — community reports (operator kits): 砾's normal attack hits twice at 50 % 伤害倍率 (a 频次 enemy loses 2), 乌尔比安's S3 moves only onto his own board (never behind the one-helper 联防 map's red gate nor onto a boss field's other half), the 「受到攻击时」 counters answer every enemy damage instance (菲莱 S2 on 深溟巢涌者's pulse, 星熊, 泡泡, 刺玫, 余, 玛恩纳, 年, 斩业星熊), an in-place 复活 restarts a deploy-timed skill so a 突袭 member jumps at once, 银灰's normal attack plays its own impact (and 雷蛇 / 初雪 / 圣约送葬人 drop a skill mode's sound); five reports pinned; §25.17 between CB2's §25.16 and CB4's §25.18; data/assets.json lists 银灰's impact (p_imp_spear_n.mp3 fetched); golden: vs feedback5 CB3's own rules — roster-002/004/005/008/010/012/016/024/033/044, bond-indomShip-low/high, bond-kazimierzShip-low/high, bond-lateranoShip-low, boss-boss_2-solo, boss-boss_4-pair/-solo, hidden-boss_8-pair/-solo, hidden-boss_9-solo, diy-051, matches solo-FUNNY-2, coop2-NORMAL-3, coop4-ABYSS-7, coop2-ABYSS-10-boosted; vs CB3 exactly what feedback5 changed since its base (CB2, CB4, CB5)

The merge:
- server/sim/battle/players.js: CB3's onOwnBoard hunk is byte-identical to CB4's (git kept one); its comment and
  docs/SIM.md's onOwnBoard row now name 乌尔比安's S3 【移动】 next to the 突袭 landing (DESIGN §25.17.2 / §25.18).
- test/sim/facing-invariance.test.js: CB3's scenario setup (onOwnBoard off on the open field) and the CB4 merge's
  突袭 test (its enemy inside the board) merged cleanly, both kept.
- data/assets.json: CB3 had regenerated it offline without 银灰's entry (his official impact file was not on disk);
  `node tools/fetch-assets.mjs --add-only` (shared public/assets, add-only) downloaded p_imp_spear_n.mp3 — 8.8 KB,
  the only new file (ok 1, skipped 7968; the 117 misses are the known upstream gaps) — and rewrote the manifest.
  Field-wise JSON compare with CB3's manifest: only audio.sfx.units.char_172_svrash = { hit: p_imp_spear_n } plus hash
  and stats (files / bytes / sfxUnits +1); against feedback5: CB3's four operators (银灰 now the spear impact and no
  S3 swing, 雷蛇 / 初雪 / 圣约送葬人 without the skill-mode impact) plus hash / stats. §25.17.6 says so.
- docs/history/0.2.0.md: §25.17 placed in order, the intro's per-stream list and workstream list name CB3.

Golden moves outside CB3's commit list: coop2-NORMAL-3 fields 砾 from round 3 (her double hit) and 刺玫 in rounds 4-7
(instrumented); solo-FUNNY-1 (in CB3's list through the counters) fields no counter operator on feedback5's path, only
砾, whose two half hits change no kill, leak, LP or end stat there, so its digest stays.

Gate: non-browser suites 5003 / 5003, npm run golden ok, test/golden.test.js 9 / 9, lint 0 errors, check:imports ok,
typecheck ok.
