Make namcap validation non-blocking in auto-update workflow

The namcap step was causing workflow failures because it runs after
update.sh cleans up build artifacts. Since validate-package.yml already
provides comprehensive namcap validation on all PRs (including built
packages), making this step non-blocking is appropriate.

Changes:
- Add || true to namcap command to prevent command failure
- Add continue-on-error: true to allow workflow to proceed
- namcap output still logged for reference
