- Add ValidationError enum with three failure modes: ConflictViability
(missing Want axis), RelationshipCoherence (empty constraints),
InterestDivergence (duplicate interest axes)
- Add validate_triangle_def() pure function enforcing all three checks
in priority order (per D-087)
- Add generate_cross_template_triangles() function that combines NPC
pools from two templates, validates each TriangleDef before processing,
and assigns ownership to template_a
- 10 integration tests in tests/triangle_validation.rs covering all
validation failure modes, ordering guarantees, cross-template span,
invalid def skipping, determinism, and intra-template isolation
