refactor(core): boundary policy as resolved capabilities, not generator-name tests (L42, step 6); R9

ResolvedLayoutSnapshotV3::finalize maps each strate's generator and interface once into capability
records (FI gradient air-gap, surface/FI landing support, passage-anchor columns, SW-to-TN floor);
ApplyResolvedStrateBoundaryBand and passage composition read those instead of generator kinds. Derived
records stay out of canonical JSON, so layout identity is unchanged. Owner hashes identical to L41;
fast/medium/full PASS on clean Clang and GCC builds; cost within noise.
Research R9 (read-only): player-visible roadmap refresh.
