PR-002.5: Application Layer — Command/Result pattern, end-to-end flow

- 8 commands (CreateFieldSession, CreateMission, RegisterArtifact,
  CreateObservation, CreateDecisionCase, ApproveDecision, StartReview,
  CompleteReview)
- 4 handlers with validation and orchestration
- Result<T, E> pattern — explicit success/failure, no exceptions
- End-to-end test: Session → Mission → DecisionCase → Approval
- 3 tests proving full flow works in memory
- ADR-007: Command/Result Pattern

Acceptance Criteria:
✅ CreateFieldSession → CreateMission → CreateDecisionCase → ApproveDecision
✅ Without PostgreSQL, Redis, S3, API, HTTP, UI
✅ Business logic verified before infrastructure attached

Next: PR-003 — PostgreSQL adapters (swap InMemory → Postgres)
