This commit fixes several issues in the core state management:
1. Fix deleteNodesAction recursive call issue
- Previously, the function recursively called get().deleteNodes()
inside the set() callback, which could cause state inconsistencies.
- Now collects all descendant IDs first in a separate pass, then
deletes them all in a single batch operation.
2. Fix memory leak in use-scene temporal tracking
- Module-level variables (prevPastLength, prevFutureLength,
prevNodesSnapshot) persisted across store re-creations.
- Now cleared in unloadScene() to release stale node references.
- Added clearTemporalTracking() helper function.
3. Remove unused variable in wall-system
- Removed debug variable 'useFrameNb' that was declared but never used.
4. Fix requestAnimationFrame in updateNodesAction
- Previously used RAF without cleanup, causing multiple queued
callbacks when updates happened rapidly.
- Now uses a single tracked RAF with cancellation support.
