watch cache hooks.

Measure hit, miss, set, delete, and evict events as live traffic moves through a MemoryCache.

The cache wires hooks for onHit, onMiss, onSet, onDelete, and onEvict.
The hit rate is calculated from reads only: hits / (hits + misses).
burst runs ten mixed operations so the event stream can show hits, misses, writes, deletes, and evictions together.
reset clears the counters and creates a fresh cache with maxSize: 5 and a 30s TTL.
