The 1.0 to 1.1 upgrade queued a sparse_only backfill item for every existing chunk whether or not pgedge_vectorizer.enable_hybrid was on, and the worker raised an ERROR for each of them, so every item failed on every attempt until it reached max_retries. On a database with tens of thousands of chunks that filled the log for days. The backfill now checks enable_hybrid, as reprocess_chunks() already does, and reprocess_chunks() queues the work if hybrid is enabled later. The worker completes a sparse-only item while hybrid is off rather than raising, since its dense embedding is already in place and there is nothing else for it to do, which also clears items an earlier upgrade has already queued. Closes #83

The worker initializes the provider only when a pulled item requires a dense embedding. When hybrid search is disabled, the worker logs and completes sparse-only items that are already queued. Regression tests cover upgrade queue counts with hybrid search on and off, and verify worker completion without changing the chunk’s dense embedding. Priority: ➖ Normal Severity of issue fixed: Medium Merge Risk: ⚪ Minimal · up to Sparse-only work is skipped during upgrades when hybrid search is disabled, and already-queued sparse-only work can complete without a provider.

- Around line 1825-1838: Update process_queue_batch() to detect batches
containing only sparse-only items that can be completed while hybrid search is
disabled, and bypass provider resolution and initialization for those batches.
Preserve provider setup for batches that require embedding work.

A pull made up entirely of sparse-only items never calls the provider, so a missing or unusable one should not fail it.
