- Add prebuild script that temporarily removes 'declare' keyword from litegraph TypeScript files
- Add restore script to revert files to original state after i18n collection
- Update collect-i18n script to use prebuild/restore workflow
- Add babel dependencies for TypeScript transformation
- Update playwright.i18n.config.ts with global setup/teardown
This fix addresses an issue where Playwright's Babel transformation couldn't handle TypeScript 'declare' fields in litegraph classes, causing the i18n collection to fail.
Fixes the issue where 'pnpm collect-i18n' would fail with:
"TypeScript 'declare' fields must first be transformed by @babel/plugin-transform-typescript"
