- Document wsId/header coupling in chat queries (cache key vs API call)
- Extract finalizePending helper to reduce duplication across 4 WS handlers
- Store chat store handle in module-level variable for consistency with
auth/workspace stores in CoreProvider
- Remove redundant ./chat/store package export (covered by ./chat barrel)

Move chat queries, mutations, and store from apps/web/core/chat/ and
apps/web/features/chat/store.ts to packages/core/chat/. Refactor store
to use createChatStore({ storage }) factory pattern (mirrors auth store)
so it works in both web (localStorage) and desktop (Electron) without
direct browser API access. Register chat store in CoreProvider.initCore.
