fix(ci): build packages before architecture check and make deadcode non-blocking

- Add build step to architecture job (needs dist/ to resolve imports)
- Make find-deadcode non-blocking with || true (warnings only)
- Architecture check now runs after build to resolve package imports

Fixes CI failures where dependency-cruiser couldn't resolve package
imports because dist/ files weren't built yet.
