fix: resolve collect-i18n babel transformation issues

- Created configurable babel-plugin-inject-globals to inject browser setup
- Added setup-browser-globals.mjs for browser environment mocking
- Moved babel plugin files to scripts directory for better organization
- Removed dependency on import order by using babel transformation
- Made plugin options configurable (filenamePattern, setupFile)
- Updated tsconfig.json to include playwright config and scripts

This fixes the ReferenceError: location is not defined issue that occurred
when running pnpm collect-i18n, ensuring the command works reliably
regardless of import auto-sorting.
