Refactor and extend role dependency resolution:

- Introduced module_utils/role_dependency_resolver.py with full support for include_role, import_role, meta dependencies, and run_after.
- Refactored cli/build/tree.py to use RoleDependencyResolver (added toggles for include/import/dependencies/run_after).
- Extended filter_plugins/canonical_domains_map.py with optional 'recursive' mode (ignores run_after by design).
- Updated roles/web-app-nextcloud to properly include Collabora dependency.
- Added comprehensive unittests under tests/unit/module_utils for RoleDependencyResolver.
