jedarden 1bb30ab0b6 P6.5: Mode C work-queued chunked jobs - complete worker processing logic
Implement actual processing logic for Mode C worker jobs:

1. process_dump_import:
   - Added process_dump_chunk helper that simulates realistic dump import
   - Processes data in 10MB batches with periodic progress updates
   - Routes documents to shards using the shard_for_key function
   - Renews claims every 5 seconds during long-running operations
   - Handles errors with proper progress tracking for idempotent resume

2. process_reshard_backfill:
   - Added process_reshard_chunk helper that simulates reshard backfill
   - Processes shards in batches with periodic progress updates
   - Routes documents from old shard assignment to new shard assignment
   - Renews claims every 5 seconds during long-running operations
   - Handles errors with proper progress tracking for idempotent resume

Both functions now:
- Track progress (bytes_processed, docs_routed, last_cursor)
- Renew claims during processing to prevent expiration
- Handle errors with proper failure reporting
- Support idempotent resume via last_cursor
