Greptile Summary

This PR hardens the Bunny Database client and migration transaction behavior.

• Adds configurable transaction modes, guarded rollback handling, transaction-statement validation, and batch failure indexing.
• Normalizes timeout, transport, and malformed-protocol failures as DatabaseError.
• Improves numeric binding and typed SQL-template behavior.
• Applies migrations with BEGIN IMMEDIATE and updates package documentation, tests, and build configuration.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the current constructor preserves both positional forms described in the previous threads, including calls with an omitted code and a supplied status.

Important Files Changed

Filename	Overview
packages/database-client/src/client.ts	Adds transaction modes, guarded batch rollback, statement validation, timeout validation, and normalized transport errors without leaving a blocking issue.
packages/database-client/src/errors.ts	Extends structured error metadata while preserving both previously reported positional constructor forms.
packages/database-client/src/protocol.ts	Adds protocol validation and revised numeric binding behavior without an eligible blocking follow-up finding.
packages/cli/src/commands/db/migrations/client.ts	Requests an immediate transaction for migration batches to acquire the write lock up front.
packages/database-client/src/client.test.ts	Expands coverage for batch modes, rollback guards, constructor compatibility, malformed responses, and typed SQL templates.
