Summary

Like UseState, but the value survives unmount/remount via an in-memory cache. On first mount, uses cached value if available, otherwise uses initialValue. Value is saved to cache on unmount.

Discussion

Spec 033 §2. The cache is currently process-wide (Default) and bounded by an LRU policy. The two-arg form will trigger an analyzer warning in a follow-up release; new code should use the three-arg overload to make the intended scope explicit.
