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
