Add chunk_max_bytes and chunk_count columns to embedding_metadata to support config drift detection and adaptive dedup sizing. Includes a partial index on sentinel rows (chunk_index=0) to accelerate the drift detection and max-chunk queries. Also exports LATEST_SCHEMA_VERSION as a public constant derived from the MIGRATIONS array length, replacing the previously hardcoded magic number in the health check.
