sqlfu

Use when working in a project that uses sqlfu: a SQL-first toolkit with `sqlfu.config.ts`, `definitions.sql`, migrations, checked-in query files, generated TypeScript wrappers, and commands such as `sqlfu draft`, `sqlfu migrate`, `sqlfu generate`, `sqlfu check`, or `sqlfu goto`.

Vendor and update the sqldef sqlite3def implementation in this repo by porting the upstream Go code to TypeScript under `packages/sqlfu/src/vendors/sqlite3def` and porting the relevant upstream sqlite3def tests to Vitest. Use when Codex needs to scaffold or refresh the vendored sqlite3def implementation, inspect the upstream `sqldef/sqldef` GitHub repository, update vendored tests first, then implement source changes until the relevant tests pass.
