3 people ab87a3f825 fix: buffer cm.Reader in BM25 streamOneFile to reduce IO syscalls (#48845) ...

## Summary
- Wraps `cm.Reader` (S3/MinIO HTTP body) with `bufio.NewReader` in
`streamOneFile` before creating the TeeReader
- `DeserializeFromReader` calls `binary.Read` which reads 4/8 bytes per
call; without buffering, each small read hits the remote reader
directly, causing excessive IO operations during preload parsing
- With `bufio.Reader` (default 4KB buffer), small reads are served from
the buffer, reducing remote IO to ~1 per 4KB

## Test plan
- [x] Existing `TestIDFOracle` tests pass
- [x] Verified via profiling that IO syscall count drops significantly
during BM25 preload
