Zhengchao An cf056b39e3 fix(core-storage): fix critical correctness defects from core-storage reliability audit (#4222)
* fix(core-storage): fix critical correctness defects from core-storage audit

Fixes verified defects found in a deep audit of the core storage path
(erasure coding, disk persistence, quorum, heal, replication resync):

- ecstore/disk: rewrite live xl.meta atomically (temp+rename) in
  delete_versions_internal and write_metadata instead of in-place
  truncate, which exposed torn metadata to concurrent readers and
  crashes on the DeleteObjects hot path
- ecstore/erasure: allow heal to reconstruct from exactly data_shards
  bitrot-verified sources; requiring data_shards+1 made objects
  permanently unhealable after losing parity_shards disks
- ecstore/set_disk: direct-memory inline GET applied the erasure
  distribution permutation twice (shuffled inputs re-indexed through
  distribution), concatenating wrong shards into the response body in
  degraded reads; collect from canonical disk-ordered inputs
- ecstore/set_disk: heal now preserves the committed inline layout
  instead of recomputing it with a hardcoded unversioned threshold,
  which split quorum identity of healed replicas and caused endless
  re-heal churn
- ecstore/replication: resync results channel switched from
  broadcast(1) to mpsc; a lagged broadcast receiver ended the stats
  collector and every subsequent failure went uncounted, letting
  failed resyncs be marked completed
- ecstore/replication: ignore an empty persisted resync checkpoint;
  resuming with one skipped every object and marked the resync
  completed without replicating anything
- ecstore/replication: fix inverted not-found error classification in
  replicate_object/replicate_delete logging paths
- ecstore/erasure: guard decode paths against zero block_size or
  data_shards from corrupt on-disk metadata (divide-by-zero panic)
- ecstore/disk: os::read_dir no longer consumes the entry limit on
  entries it does not return (is_empty_dir misjudgment); create_file
  opens with O_TRUNC to avoid stale trailing bytes
- filemeta: treat Some(nil) version id as a null version in
  matches_not_strict; disk-loaded headers never store None, so the
  mod_time quorum guard for unversioned overwrites never fired and an
  interrupted overwrite could displace the committed version in merge
- filemeta: fix msgpack skip lengths for fixext (missed the ext type
  byte) and ext16/32 (over-skipped) unknown fields
- filemeta: return FileCorrupt instead of usize underflow when
  xl.meta is truncated inside the CRC trailer
- filemeta: surface delete-marker insertion failure in delete_version
  instead of reporting success when the data dir is shared

* fix(replication): drop duplicate cfg(test) etag import from boundary module

The test module already imports content_matches_by_etag locally, so the
top-level cfg(test) import is unused under -D warnings and fails clippy.
