feedback5 WX: the 39 summon models no web dump carries come from the local client (extract.py TOKEN_SPINES) and are drawn instead of the avatar diamond when data/local-assets.json lists them

- tools/local-extract/extract.py TOKEN_SPINES (`--only spine/token`): each token's battle prefab in the
  battle token packs (pkgrps/btl_pfb_tokens_*.ab; the Windows build has all 39, the iOS build lacks
  btl_pfb_tokens_0), the skeleton of its Front (or only) Spine renderer, written to
  public/assets/local/spine/token/<id>/ like the enemy models (sized pma atlas, premultiplied pages;
  the newer RGBA pages keep their own alpha). The enemy writer is shared (write_spine; the two enemy
  models re-extract byte for byte). The skinpack job of 乌尔比安's block is gone: it extracted
  nothing, and that token draws no model in the game (nor do 圣聆初雪's, 酒神's, 贝洛内's and
  予愿安洁莉娜's hidden tokens: no Spine renderer, no avatar in either install).
- tools/assets/local-token-spines.json (committed, `fetch-assets --local-spines`) → data/assets.json
  tokens[id].spineLocal for 35 自选 summons, 凯瑟琳's 爬行号·防护单元 and 凛御银灰's three 风雪之眼; the
  manifest is the same with or without the extraction (JSON diff: only the 39 spineLocal entries and
  the hash). spine.mjs LOCAL_SPINE_ROLES maps clips the resolver cannot read (电弧's 戴乌 C_Skill1_*,
  酒神's 本能的召唤 Loop / End, 白铁's platforms End, 战术锚点 on its Default pose) [ASSUMED where named].
- assets.js spineEntry: a token resolves its spineLocal like an enemy (no web model behind it: the
  diamond stays when it is not listed or fails to load). Scale as the web tokens (UNIT.modelScale).
- setup reports an extraction without the summon models; docs: ASSETS.md "Token models from the local
  client", DEPLOY.md §6, DESIGN §13 (design/client.md), README.
- Tests: test/local-token-models.test.js (new), test/local-extract.test.js (job table, prefab walk,
  alpha merge), test/assets.test.js (the local token models load like the client does),
  test/package.test.js (the full zip ships them), test/static-local-art.test.js. Golden unchanged.
