fix: Resolve CI failures from platform-specific npm package conflicts

- Update validate-lockfile workflow to check file existence instead of npm ci
  (npm ci fails when optional platform-specific dependencies conflict)
- Add --ignore-scripts --no-optional to all build workflow npm install steps
- Prevents EBADPLATFORM errors when building on different OS/architectures
- Affected workflows: build-native, build-tiny-dancer, build-router,
  build-gnn, build-graph-node, validate-lockfile
