Architectural Deep-Dive & Systems Impact

[flake8-logging-format] Avoid behavior changes and syntax errors in fixes (G004) (#27419)

[security] Implement tarfile-ignore-zeros-true (#28680)

There is no watch mode. UI mode does not run tests again when files change, and --only-changed does not follow imports.

Bun loads modules itself, so --tsconfig and the JSX options in tsconfig.json have no effect, and custom ESM loaders are not supported.
