feat: combine ADR-029/030/031 + DDD domain model into implementation branch

Merges two feature branches into ruvsense-full-implementation:
- ADR-029: RuvSense multistatic sensing mode
- ADR-030: RuvSense persistent field model (7 exotic tiers)
- ADR-031: RuView sensing-first RF mode (renumbered from ADR-028-ruview)
- DDD domain model (6 bounded contexts, event bus)
- Research docs (multistatic fidelity architecture, SOTA 2026)

Renames ADR-028-ruview → ADR-031 to avoid conflict with ADR-028 (ESP32 audit).
Updates CLAUDE.md with all 31 ADRs.
