feat: Complete VS-02 DOMAIN - SecurityMaster sync policy (Batch 1 - 3/7)

Implements pure domain logic for security master synchronization:
- Conflict resolution (last-write-wins by PublishedAt)
- Idempotency key generation
- Rollback detection
- Rule validation and active-time checking
- 13 unit tests: 13/13 PASS

AGENTS.md v16.0 compliance:
 Necessity: WBS VS-02 DOMAIN phase
 Simplicity: Pure logic, no I/O, deterministic
 SOLID: Single responsibility (policy only)
 Guardrails: Idempotent, versioned, rollback-safe
