Optimization for hardDeleteMany to use bulk operations instead of sequential deletes.

What:

  • Changed hardDeleteMany to use bulkDelete for both file_meta and file_blobs.
  • Refactored hook logic to batch 'before' and 'after' hooks around the bulk operation.

Why:

  • Previous implementation performed N+1 (actually 2*N) DB operations for N files.
  • New implementation performs constant 2 DB operations regardless of N (plus hook overhead which is now batched in logic).

Measured Improvement:

  • Verified via unit test app/db/__tests__/files-delete.test.ts that the number of DB delete calls went from N (per table) to 1 (per table).
  • This significantly reduces transaction overhead and IPC cost for IndexedDB.

Refactors `hardDeleteMany` in `app/db/files.ts` to use `db.file_meta.bulkDelete` and `db.file_blobs.bulkDelete`.
This resolves an N+1 query performance issue where deletions were performed sequentially in a loop.

Key changes:
- Replaced sequential `delete` calls with `bulkDelete`.
- Grouped hook executions: all 'before' hooks run first, then bulk deletions, then 'after' hooks.
- Added `app/db/__tests__/files-delete.test.ts` to verify the behavior and ensure correct hook and DB call counts.

This reduces the number of DB operations from 2*N to 2 for N files.
