fix(tier): recover (#3182)

* fix(tier): stop sending nil/garbage versionId to warm backend S3

Three bugs caused NoSuchVersion errors when reading tiered objects:

1. warm_backend_s3sdk: GET and DELETE ignored rv/range opts entirely —
   fixed to forward version_id and byte-range to the SDK request.

2. version.rs (MetaObject + MetaDeleteMarker): transition_version_id was
   parsed with unwrap_or_default(), turning invalid/wrong-length bytes
   into Uuid::nil(). The nil UUID was then serialized and sent as
   ?versionId=00000000-... to the tier backend -> NoSuchVersion.
   Fixed: .and_then(.ok()).filter(!is_nil()) so only valid non-nil UUIDs
   are forwarded as versionId.

3. bucket_lifecycle_ops: add debug/error logs in
   get_transitioned_object_reader to record tier, tier_object, and
   tier_version_id before and on failure of the tier GET.

Also adds tier transition fields to dump_fileinfo example for offline
xl.meta inspection, and fixes Docker build (cargo path + entrypoint).
Adds CLAUDE.md with tier architecture and debugging notes.

* remove branch

* Add tests and fix cargo path, add load to build-docker

* update documentation (CLAUDE.md)

* more fixes for recover

* More fixes to ILM recover

* final fix

* chore: add missing-shard first-scene diagnostics (#3213)

chore(ecstore): add missing-shard first-scene diagnostics

Log rename_data quorum context behind RUSTFS_ISSUE3031_DIAG_ENABLE so partial-disk success can be correlated with later missing shard reads.

Also log put_object commit success and tmp cleanup boundaries to capture when successful quorum writes are followed by tmp_dir cleanup.

* fix test anmd fmt

* fix cargo path
fix test

* fix(tier): format copy_object self-copy guard
