Get effective (composed) alignment with provenance
Returns the composed canonical alignment card (platform → org → team → agent cascade applied) with _composition.field_provenance always populated. The provenance map carries per-key {layer, layer_id?, kind?} entries showing which authoring scope contributed each leaf. Caller-aware redaction: layer labels (platform / org / team / agent / derived) are always visible; layer_id is only revealed to callers who can read that scope. cards-as-primitive Phase 4 W2.2.
