revert(hooks): roll back the three snapshot-consumer migrations to pre-71a0eee state

The migrations of useSessionInfo, useChatWidget.ownUserId and the
AvatarInfo Ignore/Unignore menu to the new useSessionSnapshots hooks
were correct in code but produce a persistent runtime error in the
user's deployment:

  TypeError: (intermediate value)() is undefined
      ToolbarView ToolbarView.tsx:46

The error fires from React's render loop on the first paint —
ToolbarView is the first mounted consumer of useSessionInfo, which is
why it carries the boundary message. Two attempted fixes did not
resolve it on the user's side:
- 790ad2b: vite alias forcing @nitrots/nitro-renderer to source index.ts
- c35a2d4: defensive typeof guards on every Manager method call inside
  useSessionSnapshots (so a missing method degrades to a frozen default
  rather than calling undefined)

Both are correct defenses but the error persists, meaning the failure
mode is upstream of those guards. Rather than burn more cycles
remote-debugging, roll back the three consumer migrations:

- useSessionInfo: restored to the pre-71a0eee shape — 5 useState
  fields driven by useMessageEvent<UserInfoEvent, FigureUpdateEvent,
  UserSettingsEvent>. The five consumers (ToolbarView, HcCenterView,
  ChatInputView, AvatarInfoPetTrainingPanelView, InfoStandWidgetPetView,
  AvatarInfo{Avatar,Pet,OwnPet}View) get the same destructured shape
  they had before this session.
- useChatWidget.ownUserId: restored to `GetSessionDataManager()?.userId`
  (synchronous, captured at mount). Loses the session-change reactivity
  but matches the previous, working behaviour.
- AvatarInfoWidgetAvatarView Ignore/Unignore: restored to
  `avatarInfo.isIgnored` (captured by AvatarInfoUtilities at click
  time, not reactive). Loses the live-toggle if the user is
  ignored/unignored while the popup is open — known small regression,
  worth it for stability.

Kept intact:
- The useSessionSnapshots.ts hook file itself, with defensive guards,
  so the API stays available for any future opt-in consumer.
- 790ad2b vite alias for the umbrella, still useful as defence in
  depth for future migrations.
- All the other non-snapshot modernizations from this session
  (usePetPackageWidget reducer, useWordQuizWidget bug fix,
  useChatCommandSelector Zustand store, useAvatarInfoWidget typed
  globalThis accessor).

Verification: yarn typecheck clean, yarn test 207/207, yarn build green.
The toolbar should boot without the error now — the call chain on the
first paint no longer touches the new useExternalSnapshot / snapshot
getter path.
