Pull request overview

Adds a --watch mode to the sqts compiler so it can recompile automatically on file changes, while also expanding the test suite around SQL parsing/introspection and compiler helpers, and enabling package/type linting in the build configs.

Changes:

• Add watch mode (--watch) to the sqts compile CLI and implement a chokidar-based watcher.
• Refactor/add Bun tests (and snapshots) for SQL parsing, schema introspection, and compiler utilities.
• Enable publint / attw in tsdown configs and add corresponding dev dependencies.
