perf(get,heal): fix GET hot-path overhead and heal checkpoint scaling (#4237)

perf(get,heal): land verified fixes for backlog #800-#804

Five fixes from the GET-path performance audit and scanner/heal
completeness audit (rustfs/backlog#800..#804), each verified locally:

- backlog#800 (heal checkpoint O(N^2)): ResumeCheckpoint object sets are
  now HashSet (Vec::contains was O(n) per healed object; 1.5ms at n=1M
  vs 11ns measured), and per-object checkpoint/resume-state persistence
  is batched (1000 mutations / 5s) instead of rewriting the whole file
  per object. complete_page() prunes the sets at page boundaries so
  memory stays bounded; positions still persist unconditionally and
  legacy Vec-format checkpoints still deserialize.

- backlog#801 (DiskInfo.healing never set): erasure-set heal now writes
  a healing marker (.rustfs.sys/healing.bin) on the disks it rebuilds
  (endpoints plumbed via HealRequest/HealTask.heal_endpoints from the
  auto disk scanner) and clears it on success. LocalDisk::disk_info
  surfaces the marker, so scanner heal coordination, lock selection and
  admin/metrics healing counts see the rebuild.

- backlog#802 (cache probe after data read): new GetObjectBodyCacheHook
  in ecstore lets the app-layer object data cache serve the body inside
  get_object_reader, after metadata quorum resolution (etag known) but
  before the erasure shard read/decode. Previously a hit still paid the
  full disk read. Hook is None/no-op when the cache is disabled.

- backlog#803 (GET hot-path redundant work): ObjectInfo is cloned for
  event notification only when an event will actually be built (GET and
  HEAD paths; events are currently suppressed so the clone was pure
  waste); get_opts/put_opts/del_opts resolve bucket versioning with one
  metadata-sys lookup instead of two; skip_verify_bitrot and
  get_lock_acquire_timeout env reads are cached via OnceLock; the
  io-priority metric is no longer double-counted; GetObject input fields
  are cloned selectively instead of cloning the whole input.

- backlog#804 (disk permit starvation): the disk-read permit wait is now
  bounded (RUSTFS_OBJECT_DISK_PERMIT_WAIT_TIMEOUT, default 5s, 0 =
  previous unbounded behavior); on timeout the GET proceeds without a
  permit and the bypass is counted. DiskReadPermitReader also releases
  the permit at body EOF instead of holding it until the client drops
  the stream.

Verification: make pre-commit; cargo clippy -D warnings on the four
changed crates; full rustfs lib suite (2096 tests) green; rustfs-heal
lib suite green with new unit tests for checkpoint pruning/legacy
format/throttle, permit EOF release, and the cache hook (hit + SSE
skip). The heal_integration_test and one set_disk listing test fail
identically on unmodified main (pre-existing global-state ordering
flakes, verified via git stash A/B).
