* fix(ecstore): skip hidden metadata in walk limit
* fix(ecstore): match walk limit to visible versions
* fix(ecstore): avoid decoding all versions for limit
* fix: return 503 on lock contention instead of 500
When concurrent PUTs to the same key contend for the namespace write
lock, lock timeout and conflict errors were wrapped as
StorageError::other(...) → StorageError::Io(...), which fell through
to S3ErrorCode::InternalError (500) in the error mapping.
Only QuorumNotReached was correctly mapped to ServiceUnavailable (503);
all other lock errors (Timeout, AlreadyLocked, etc.) became 500.
Fix: map_namespace_lock_error now returns StorageError::Lock(err) for
non-quorum lock errors, and StorageError::Lock is mapped to
S3ErrorCode::ServiceUnavailable in the HTTP error conversion.
Affected paths:
- crates/ecstore/src/set_disk/lock.rs
- crates/ecstore/src/store/object.rs
- crates/ecstore/src/store/bucket.rs (make_bucket, delete_bucket)
- rustfs/src/app/object_usecase.rs (copy_object)

* fix(readiness): gate on lock quorum health
Include distributed lock quorum in runtime readiness decisions and expose the signal in health responses.
Map namespace lock quorum failures to ServiceUnavailable instead of InternalError so clients can safely retry while keeping quorum enforcement unchanged.
* fix(ecstore): restore namespace lock error decoding
Add the missing from_u32 arm for NamespaceLockQuorumUnavailable and cover the numeric roundtrip in error tests.
