weisd ea74fa7a95 fix(heal): rebuild parity shards during repair (#3086)
Object repair rebuilt missing data shards but left missing parity shards unrecreated. A parity-only repair could therefore complete without restoring the shard contents.

Add a repair-specific reconstruction path that regenerates parity after data shards are available, while keeping normal read decoding data-only. Also shut down repair writers after all blocks are written.

Constraint: Preserve read-path decode behavior and limit parity regeneration to repair.

Confidence: high

Scope-risk: moderate

Directive: Do not route read decoding through parity regeneration without measuring the cost.
