Three targeted regression tests covering bugs fixed in the embedding
pipeline hardening:
- overflow_doc_with_error_sentinel_not_re_detected_as_pending: verifies
that documents skipped for producing too many chunks have their
sentinel error recorded in embedding_metadata and are NOT returned by
find_pending_documents or count_pending_documents on subsequent runs
(prevents infinite re-processing loop).
- count_and_find_pending_agree: exercises four states (empty DB, new
document, fully-embedded document, config-drifted document) and
asserts that count_pending_documents and find_pending_documents
produce consistent results across all of them.
- full_embed_delete_is_atomic: confirms the --full flag's two DELETE
statements (embedding_metadata + embeddings) execute atomically
within a transaction.
Also updates test DB creation to apply migration 010.
