0.2.4-dev: round-29 community fixes and the official shared card pool

- Shared card pool and item stock as in the official mode (the owner's request, from the 路标档案馆 video and public notes): solo low-tier exceptions, co-op operators x2, shared item stock with special-item exceptions, normal / advanced occupancy 1 / 2, re-check on buy, 机变 exhaustion, release on consume / destroy / elimination; 整备 never exceeds stock; invariant held <= cap.
- 突袭: one taunt-first reselect right after a revive (the owner's rule); ordinary polls and redeploys keep the 0.2.3 rule; a revive on an enemy's tile stays. #475: online boss / hidden-boss Raid may land on the empty half (owner-limited scope).
- 浊心斯卡蒂 S1 x 坚守 no longer bounce redirected damage, and the two shares conserve the hit (idea of PR #464 by @HappyTanuki).
- Operator fixes adapted from PRs by @Xinglan233 (#459 哈洛德 S2 elemental trigger, #460 涤火杰西卡 shield on the four adjacent tiles, #461 家族徽章 first hit after stealth, #462 松果 S2 regrow per deploy); 克莱门莎 S2 splash 1.1 / 100% ATK and air auto-trigger (#467); 白面 copying 歌蕾蒂娅 / 余 skips the three-member condition (#473, the owner's video).
- 香槟炸弹 is not chosen by friendly auras / heals (PR #468 / #476 by @Siornya); 琳琅诗怀雅 coin balance (PR #450 by @IceCodeNew); Touch prep display (PR #451 by @YinqiMargatroid); lobby header (PR #471 by @YuriRestia); Japanese UI terms (PR #448 by @scutkane).
- AI-only boss countdown grace, render-failure cache / recovery without restarting a battle, device units kept on a same-field re-entry, DIY detail / skill previews, large-text result buttons.
- golden: battle families equal 0.2.3 except diy-135 / diy-136 (克莱门莎); all 18 release matches move through the shared pool, every flip named in docs/history/0.2.4.md §29.12; two coverage scenarios added.

 Equipment (research 04 §2 + addendum, 09 §1.2): 2 slots per chess; a third item on a full carrier replaces the equipped item `replaceUid` names (the replace dialog's pick, official `UseEquipUp.unloadInstId`; absent ⇒ the oldest; a uid not equipped on the target ⇒ `BAD_TARGET`, nothing changes) and the replaced item is destroyed. A consume-on-equip item (盟约之币, 博士投影 …) on a full carrier replaces the same way before it resolves, so the carrier is left with a free slot (the normal 博士投影 takes it until the next round start); a target its effect refuses (博士投影 on an elite) keeps both items — PRTS 卫戍协议/帮助 "达到上限强行佩戴会改为替换装备" names no exception (GitHub #263; the client opens the replace dialog for it, `equipReplaces`). Equipped items are otherwise **locked**: `destroy` (销毁) accepts hand / temp items only (`BAD_TARGET 'equipped items are locked'`); equipment goes back to the hand only when its carrier merges, is sold, or is destroyed by 突变细胞's transformation (the cell itself returns too; PRTS 帮助 "在失去该干员（干员出售、销毁、合并等）…时自动卸除", §21.1) — a sale is refused with `HAND_FULL` when there is no room for it; returned equipment is stowed before the operator a transformation gains and before a merge elite's summon cards, and every path that hands the player an item — returned equipment included — ends with the auto-merge, so no player holds two identical mergeable normal items (§21.7).

 **Temp overflow (临时整备区, row 8; user playtest #3 item 3).** Passive gains that find the hand full (merge elites, grants — the operator a 突变细胞 transformation gains included, §21.1 —, battle-result rewards, equipment returned by a merged / sold / transformed carrier) overflow into the 5 temp slots, and Ready is refused while any is occupied (official "直到溢出情况排除才可开始进行作战"). A temp piece is resolved — a chess sold back to the pool with its summons removed, items destroyed, a summon stack removed (it comes back at the next round start, PRTS "干员所属召唤物会于下一回合返还", §20.1) — only at the deadline of the **first prep in which its player could act on it** (`PlayerState.tempDue(piece)` vs `prepsEnded`; every write into a temp slot goes through `_putTemp`, which records it): a piece that arrived during a prep before Ready is due at that prep's end; one that arrived after Ready or during the `<休整期结束时>` effects, or outside PREP (COMBAT, 联防, SETTLE — battle-result grants, a SETTLE merge's elite, returned equipment —, the next ROUND_START, 机变) is kept, visible and usable (move to a free hand slot, place, equip, use, destroy, sell) through the **next** prep. Un-readying (`setReady(false)`) makes whatever arrived while ready due at the current prep. ROUND_START no longer wipes temp (it used to destroy what SETTLE had put there before the player ever saw it). A merge's elite whose merge consumed a deployed copy takes that copy's tile and facing (§20.11); otherwise it goes to the hand, overflowing into temp (also outside PREP). `server/match/audit.js` (`tools/matchrun.mjs --check`) tracks the arrivals itself and flags any temp piece that outlives its due prep. The UI frames the row on the board with the rule (§17.5).
