* feat(admin): expose replacement recovery status

Surface the local durable replacement recovery snapshot in the background heal status response so operators can tell whether replacement cleanup is definitive or still pending.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(heal): keep replacement status compatible

Keep the existing background heal status response wire-compatible while retaining the Linux mount lease cleanup needed for the replacement recovery branch.

Co-Authored-By: heihutu <heihutu@gmail.com>

* style(ecstore): match linux mount lease formatting

Keep Linux rustfmt output stable for the replacement mount lease comparison.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(ecstore): qualify mount lease test constant

Use the disk module path for the format config constant in the Linux mount lease regression test.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(ecstore): keep procfd mount roots directory-safe

Use a procfd path with an explicit directory component so Unix directory guards can open the replacement mount lease root with O_NOFOLLOW while preserving handle-relative I/O semantics.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(ecstore): delete empty leased buckets via dirfd

Use the held mount lease fd as the parent for non-force empty bucket deletion on Linux so procfd-rooted paths do not get rejected as BucketNotEmpty. Also make the download-part OpenOptions truncate behavior explicit and keep fsync test recording stable across procfd canonicalization.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(ecstore): scan leased bucket paths for emptiness

Use the local disk I/O root for bucket emptiness probes before non-force bucket deletion and table-bucket metadata checks. This keeps validation on the same mount instance as the subsequent local disk delete path.

* fix(heal): classify flat replacement intent corruption

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(heal): keep transient resume loads retryable

Classify malformed legacy replacement state as blocking corruption while preserving disk and transient load failures for retry. This avoids permanently blocking replacement recovery on temporary storage errors.

under `admin/high`. If scanner work grows but admin work remains blocked, treat
that as heal queue pressure rather than scanner pacing pressure.
## Replacement Recovery Completion
`POST /v3/background-heal/status` is an execution-queue view. `state=idle`, zero queue and active counts, an online disk, a readable object, or acceptance of an Admin deep-heal request do not independently prove that a replacement disk contains every erasure shard.
Treat replacement recovery as verified only after the repair task has completed for the exact replacement instance and an operator has confirmed the target disk contains the expected `xl.meta` and data parts for every relevant object version. A replacement that is not mounted, is unsafe to format, loses its marker, or returns a partial target outcome must be treated as deferred or incomplete rather than complete.
The v3 route and its peer status protocol preserve their existing fields for mixed-version clusters. A new node must not infer replacement completion from an old or unavailable peer; regard that information as unknown or degraded until every required peer can report the same replacement instance and verified completion. Do not automate destructive replacement actions from an `idle` observation alone.
Replacement resume and checkpoint files use an independent on-disk schema. A newer reader rejects a future schema rather than continuing with data it cannot interpret, while an older binary cannot safely enforce the new generation fence because it may ignore fields it does not know. Do not roll a cluster back after a replacement generation has started. Complete that recovery with the current-or-newer release; if it cannot complete, keep that version for diagnosis rather than deleting its durable records or continuing with an older binary.
