…1637) (#3721) Audit current pool defaults (COPY_BUFFER_SIZE = 128 KiB, max_buffers = available_parallelism()), document the workloads they were tuned for, and call out where the defaults underprovision (1M-file parallel bursts) and overprovision (sequential single-threaded transfers, long-lived daemon mode). Cover the adaptive grow/shrink policy from #1638-#1641, the OC_RSYNC_BUFFER_POOL_SIZE and OC_RSYNC_BUFFER_POOL_STATS env vars from #1643, and the memory cap interaction from #1188. Close with sizing rules of thumb for operators and open questions for the pending #1642 benchmark.
