feedback6 R21D: a consume-on-equip item on a full carrier opens the replace dialog and replaces the picked item first (GitHub #263, PR #264); golden: matches 10 of 18 moved (a targeted consumable on a full carrier now destroys the oldest item), the rest unchanged

PRTS 卫戍协议/帮助 §装备: 「达到上限强行佩戴会改为替换装备：指定一件已佩戴装备替换为将要佩戴的装备，并销毁被指定的装备」,
no exception for the 装备时销毁 items. Before: a normal 博士投影 opened no dialog and its kept item pushed the OLDEST
equipped item out (replaceUid ignored); 盟约之币 and the other consumables kept both items.

- server PlayerState.equip (player/items.js): on a full carrier the consume path takes the pick (replaceUid, else the
  oldest) off before onEquip (_takeReplaced), destroys it (onDestroy reason replace) once the effect went through —
  the normal 博士投影 takes the freed slot —, and puts it back at its index when the effect refuses (博士投影 on an elite:
  nothing destroyed)
- client gameLogic equipReplaces: the replace dialog opens for every item on a full carrier, consumables included,
  except an attaching item that completes an item merge and a 博士投影 on an elite; itemAttaches removed
- bots (itemTarget): a consumable whose effect is the same on anyone goes to a carrier with a free slot first (PR #264)
- docs: design/match.md equipment rules, META §2.5, PLAYING 装备 row, research 04

 Summons (§20.1): an operator on the board sends its manually deployable summons to the hand — deploy-limit copies in one stack, no deploy slot (tokens.json `placeable`, `gamedata.placeableTokens`); moving or swapping it sends its placed summons back to their stack, withdrawing or selling it removes them. A range-bound summon (tokens.json `ownerRange`: 狼群, 流形) goes only on a tile of its owner's attack range (`PlayerState._legal` / `summonRange`); in a swap each piece is checked from the tile it ends on; an in-place re-orientation or promotion that leaves it outside sends it back to its stack with a toast (one still inside stays [ASSUMED], user-confirmed 2026-10-03), and a re-orientation whose lifted summon would have no room is refused with `HAND_FULL`; on the other paths it leaves the board and returns at the next round start (§21.3).
 
-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. 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).
