Snapshot of the custom-LUT cache counters. Cumulative since process
start. Exposed for the data monitor and diagnostics. The shape is
stable: { size, maxSize, hits, misses, collisions, evictions }.
Hit rate = hits / (hits + misses). A low hit rate after many
lookups means the LRU isn't doing much (the working set exceeds
maxSize) or fingerprint collisions are forcing rebuilds.
