Fei Deng 9267745ba1 add peek_lru to LRU eviction manager ...

Add LruUnit::peek_lru(), Lru::peek_lru(shard), and Manager::peek_lru(shard)
to peek at the least-recently-used item in a shard without evicting it.
Returns None for empty shards or out-of-bounds shard indices.

This enables callers to report the eviction frontier — the age of the item
that would be evicted next — for cache observability metrics.
