docs(CLAUDE.md): refresh stale sections — snapshot consumer hooks + closed bugs

- Adopted table: add new row for the useSessionSnapshots consumer hooks
  (pilots on useSessionInfo + AvatarInfoWidgetAvatarView); bump Vitest
  count from 193/193 to 203/203; expand the Zustand row to note that
  the WiredCreatorTools panel-lifecycle hoist roadmap is closed (every
  remaining useState in that component is genuinely transient).
- Not yet table: drop the obsolete "hoist Wired Creator Tools derived
  state" row (done in monitorSnapshot/selection/highlight/inline-editor
  hoists + today's three picker commits). Add a new row for migrating
  remaining session-data mirrors to the snapshot pattern.
- Patterns section: new "useSessionSnapshots" entry at the top
  documenting the 8 hook menu and which pilots already use them.
- Known open logic bugs: both previously-open races are closed
  (9d10e52 + 97c9717). Replace the section with a "no open bugs" entry
  pointing readers to docs/ARCHITECTURE.md "Recently fixed".

No code changes — pure doc refresh aligning CLAUDE.md with the
current state of the branch.

 ## Patterns to use
 
+### `useSessionSnapshots` (renderer snapshot pattern, React-side)
+
+For state that lives on a renderer Manager and is invalidated through
+`NitroEventType.*_UPDATED`, prefer the snapshot consumer hooks in
+`src/hooks/session/useSessionSnapshots.ts` over `useState +
+useMessageEvent` mirrors:
+
+```ts
+const userData = useUserDataSnapshot();           // SessionData
+const room    = useActiveRoomSessionSnapshot();   // RoomSession
+const ignored = useIgnoredUsersSnapshot();        // ReadonlyArray<string>
+const isIgn   = useIsUserIgnored(name);           // boolean, memoized
+const badges  = useGroupBadgesSnapshot();         // ReadonlyMap<number,string>
+const badge   = useGroupBadge(groupId);           // string, memoized
+const vols    = useVolumesSnapshot();             // sound volumes
+const users   = useRoomUserListSnapshot();        // ReadonlyArray<IRoomUserData>
+```
+
+Each is a thin `useSyncExternalStore` wrapper around the renderer's
+matching `getXxxSnapshot()` + subscription to the matching event.
+Snapshot references are renderer-guaranteed stable until invalidation
+— React bails out cleanly when nothing changed. Pilot adopters:
+`useSessionInfo` (userFigure / respects), `AvatarInfoWidgetAvatarView`
+(reactive Ignore/Unignore menu entry).

-| Hoist Wired Creator Tools **derived** state to the Zustand slice | UI-only flags are already hoisted (`useWiredCreatorToolsUiStore`). What's left is the event-driven derived state — `selectedFurni` / `selectedUser` / `monitorSnapshot` / `variableHighlightOverlays` — which can only move alongside their listener effects (multi-session refactor). |
+| Migrate remaining `useSessionInfo`-style mirrors to renderer snapshots | Pilot done on `useSessionInfo` + `AvatarInfoWidgetAvatarView`. Other candidates: any place that reads `GetSessionDataManager().userId/figure/clubLevel/isModerator` etc. directly in render and never re-renders on session changes. Each is a small migration; no need to bundle. |
-| Widen the component / hook test coverage | Mock layer is in place (`src/nitro-renderer.mock.ts`) and the first 2 pilots pass. Good follow-up targets: other `*State` hooks built on event reducers, `LoginView` Form Actions happy/error paths, OfferView with `useNitroQuery`. |
