fix: handle Playwright installation for specific projects only

Remove global Playwright installation that was causing "playwright: not found"
errors. Instead, install Playwright only for projects that need it (like
bi-directional) during the e2e test job.

This fixes the setup-matrix job failure and ensures Playwright is only
installed where it's actually used.
