* perf(erasure): remove UUID from clone + increase encode inflight budget
Two targeted optimizations for the erasure encoding hot path:
1. Erasure::clone() no longer generates Uuid::new_v4() per clone.
The _id field is unused in the hot path; reusing the original ID
eliminates a CSPRNG call per block encode (100 calls for a 100MB
object with 1MB blocks).
2. Default RUSTFS_ERASURE_ENCODE_MAX_INFLIGHT_BYTES raised from 8MB
to 32MB. This increases the encode pipeline depth from ~5 to ~20
blocks, allowing more read-ahead between the encoder and disk
writer stages. The per-request memory bound is still controlled
by the 8-block hard cap and the env var override.
3. Added encode_data_owned() utility method for zero-copy encoding
when the caller already owns a heap buffer (Vec<u8> → BytesMut
via Bytes::try_into_mut). Not used in the hot path yet but
available for future callers.
All 1157 ecstore tests pass. Criterion micro-benchmarks show no
regression (< 2% variance). Single-machine warp E2E tests were
inconclusive due to high variance; a dedicated multi-disk test
environment is needed for reliable E2E comparison.
