Add nodes/resolver_node.py: ResolverNode, a thin adapter that delegates to
resolve_scene (MASTER_SPEC §20).
- Required inputs scene (SCENE model) and knowledge_base (KNOWLEDGE_BASE, from
the loader node); optional config (COMPILER_CONFIG) defaulting to Config().
- Outputs (resolved_tags, warnings, errors): RESOLVED_TAGS plus surfaced
diagnostics. No compiler logic in the node.
- Registered as SceneCompilerResolver ("Resolver").
Tests: metadata/inputs, real resolution over a small in-memory Knowledge Base,
delegation + message surfacing (monkeypatched), default config, registration.
