feedback5 WM: merge feedback4 (896dd5d, the coming 0.1.4) — PRs #150 #66 #146 #74 #72 #103 #149 #109 #160 ported into the split layout

Ported by hand:
- #109 kit hunks → kits/ops (the tier files stay re-export shims): 宴 chess_char_1_18-utage.js, 野鬃
  chess_char_1_19-wildmn.js, 砾 chess_char_2_12-gravel.js, 斯卡蒂 chess_char_3_05-skadi.js, 伊内丝
  chess_char_4_04-ines.js, 缄默德克萨斯 chess_char_4_16-texas2.js, 耀骑士临光 chess_char_6_17-nearl2.js. The +/- lines
  are identical to #109's tier1/2/3/4/6 diffs.
- #109 generic.js against W5D's own-duration passives (一击即退): the deployment window is computed where #109 computes
  it, with W5D's case included. Both forms run #109's duration lifecycle (activateOnDeploy, spType 'none', the
  skill's own mods), and W5D's 冲锋号令 DP start effect is kept.
- #103 room.js through i18n phase 1: t('{name}邀请你加入卫戍协议：盟约【{difficulty}】') with the translated difficulty
  name (the Chinese text is the PR's), plus its English line in public/i18n/en.json.
- data/assets.json: feedback5's manifest plus #72's audio.bgm.combatAlts (after boss, the plan order). files +3 and
  bytes +5 037 595 as measured on feedback4; the hash is recomputed with the generator's contentHash. No other data/
  file changed.
- docs: DESIGN §5.6 (#109's timed deployment paragraph before feedback5's trigger rules; "Permanent passive skills are
  always on"), SIM §7.4 (both generic passive cases).
- Auto-merged and checked: #149 bond-bar fold (still in screens/game.js), #160 skills.js / spine.js, #109 skills.js /
  snapshot.js, #66 addon/battle.js (restTile / isDown live in sim/battle/tiles.js), #150 units.js, #72 audio.js /
  plan.mjs, #74 plan.mjs / docs.

Where the PRs met feedback5 work:
- 突袭 (W5L, GitHub #49): raidPoll counts a skill that needs no SP while it is on. That is a passive, as before, or a
  #109 deploy-timed skill while its window runs. Once the window has ended only the idle trigger is left. Without this
  change 缄默德克萨斯 / 宴 lost #49. research 02 §3.18 says so.
- Tests changed to #109's representation: bonds_addon #49 test (kind 'duration', activateOnDeploy) plus a new test
  (window over → idle trigger only), and standin.test.js's 预备干员 PASSIVE branch (the skill's mods instead of the
  generic:passive buff).

Golden regenerated on the merged code. Attribution: each PR's gameplay change was reverted alone in a scratch copy, and
all three together. With all three reverted the digests equal feedback5's exactly. Every moved scenario was replayed
and fields the unit that explains it.

  琳琅诗怀雅 S1/S2, 星熊 S2, 凯瑟琳 S1, Misery S3 as stand-in / 自选 prototype).
- #109 only (deploy-timed skill state and lifecycle; 突袭 技能就绪 limited to the window; generic 一击即退):
  roster-003/004/005/021/023/024/039/041/042/046/047, bond-egirShip-high, bond-indomShip-high,
  bond-kazimierzShip-low/high, hidden-boss_8-pair, standin-01, coop4-FUNNY-6, coop2-NORMAL-8-serverrun.
- #66 only (灵巧's aura stays only for a killed member, from its body tile): roster-028, coop2-NORMAL-3,
  coop3-ABYSS-5, coop4-ABYSS-7, solo-HARD-9-boosted.
- #109 + #160: roster-002, roster-029, bond-investShip-low, bond-raidShip-low/high, bond-suntShip-low,
  bond-visiShip-high.

 ### 2.2 Layers (层数)
 
 - Each player has one integer layer counter L per bond (23 counters). All start at 0 when the simulation starts, are never reset between rounds and are never reduced (no layer-loss effect exists in the data) [ASSUMED: never reduced].
+- `noStack: true` hides layer counts for 调和 / 协防干员 / 独行 / 绝技; it does not prohibit gains or clear stored layers. Their effects depend on member thresholds, but internal layers still participate in active-layer totals and unite ordering. [PRTS 下半盟约记录](https://prts.wiki/w/卫戍协议：盟约_下半/PRTS盟约记录): hidden-layer bonds still accept trait / strategy / equipment layer gains (review correction, 2026-10-04).
 - L is kept while the bond is inactive, but bond effects only apply while the bond is active (PRTS 盟约记录).
 - Wording contract used by every source: "使已激活的【X】层数+N" -> add only if bond X is active at the moment of the trigger; "（无需激活盟约）" -> add even if X is inactive. "自身所属盟约" = every bond of that operator; "自身已激活的盟约" = only its bonds that are active.
 - No layer cap in the data. Caps are per source: max_add_count_per_battle (layers a single garrison instance may add in one battle), max_layer (per round, e.g. 安洁莉娜 12/round). The official cap is in the client, not the data: `AutoChessBattleConst.MAX_GARRISON_STACK = 999`, `AddBondCount` stores `min(L + n, 999)` per bond (research 11 §1). Since 2026-10-01 (DESIGN §20.12) the remake stops each bond at 999 (`shared/constants.js BOND_LAYER_CAP`, `layerGainRoom`); the community agrees (巴哈姆特 12534 "每把都能999层", "沒999層的盟約情況下"; 12316 "999謝").
