- Hoshe #3: replace O(n²) Vec scan in fallback NPC assignment with
BTreeSet; prevent same NPC assigned to two roles in one triangle
- Hoshe #4: add From impls for RoleId, TriangleId, StableId, and
TriangleCrisisEventWire — eliminate fragile .0 access on newtypes
- Hoshe #5: consolidate near-identical unit tests with integration
counterparts — keep only unique tests in #[cfg(test)] module
- Tyre #3: replace O(N*M) scan in apply_resolve_triangle with
BTreeMap<TriangleId, Entity> index for O(1) per-command lookup
- Tyre #4: document &mut World on generate_intra_template_triangles
- Observer snapshot uses TriangleCrisisEventWire::from instead of
manual field mapping
