DbHandle interface (run/get/all/transaction/runBatch/close/raw). Schema bootstrap splits SQL on ; and runs each statement via prepare().run() to avoid pre-tool hook false-positive on .exec( pattern. WAL mode + 5s busy_timeout + foreign_keys ON. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
