Fix CI cooldown by replacing ALL [email protected] with 4.50.0

- Add pnpm override for [email protected]
- Systematically replace all [email protected] references in lockfile
- Replace all @rollup platform packages from 4.50.1 to 4.50.0
- This ensures CI passes the 2-day cooldown check for new packages
