Add tests, schema sync safeguards, and query/handler improvements

- Add bun test suite: SQL generator and value unit tests, plus MariaDB integration tests gated on BUN_MARIADB_TEST_DB - schema: add --dry-run and require confirmation (or --yes) before dropping tables/columns; block unapproved destructive statements - Always AND targetId with the query, regardless of searchOperator - Initialize lazily on first call; init throws instead of exiting - Generate IN (?, ?, ...) lists for IN / NOT IN - Share value binding between insert and update (booleans, embeddings, function values, "" -> NULL for non-text columns) - Keep Buffers and convert BigInt/Date without a JSON round-trip - DbSQL: report success for empty SELECT results - Run update() in a transaction with row locking - Key the client cache on the full connection config - Consolidate identifier quoting, drop dead code, merge column lookup - Read CLI version from package.json, pin @types/bun, chmod CLI on compile - Rebuild dist Co-Authored-By: Claude Opus 5.5 <[email protected]>
