fix: add tsx dependency and fix workflow step ordering

- Add tsx as an e2e devDependency (was missing, causing silent failures)
- Replace `npx tsx` with `pnpm exec tsx` throughout
- Move `pnpm install` before `playwright install` (correct ordering)
- Remove `2>/dev/null` that was hiding analyzer errors
- Add debug logging to route analysis step
- Set default working-directory for the job
