* Fix: Trigger self-heal on read when shards missing from rejoined nodes (#871)

* Initial plan

* Fix: Trigger self-heal when missing shards detected during read

- Added proactive heal detection in get_object_with_fileinfo
- When reading an object, now checks if any shards are missing even if read succeeds
- Sends low-priority heal request to reconstruct missing shards on rejoined nodes
- This fixes the issue where data written during node outage is not healed when node rejoins
