ci: use setup-vp action and update actions/checkout to v6 (#1)

## Summary
- Replace separate `pnpm/action-setup`, `actions/setup-node`, and `pnpm
install` steps with `voidzero-dev/setup-vp@v1`
- Update `actions/checkout` from v4 to v6
- Use `vp` commands directly instead of `pnpm vp`

## Test plan
- [x] Verify CI workflow passes with setup-vp action
- [ ] Verify deploy workflow runs successfully
