Issue Number: N/A Related PR: N/A Problem Summary: File cache hit ratio metrics are derived from global file cache read bytes, but warmup reads from manual warmup, periodic warmup, event-driven warmup, and rebalance-triggered warmup used to update the same counters as query reads. This polluted the query hit ratio. Mixed hit/miss reads could also be attributed to one source for the whole request. This change skips warmup updates to global file cache read metrics while preserving per-IOContext profile stats, records local/remote/peer bytes by actual returned bytes, and avoids updating metrics for failed reads. It also fixes direct-read partial continuation and no-warmup miss-only hit ratio refresh.
