git commit -m "feat(contract): enforce lifecycle-bound archive and restore transitions

Implement lifecycle-bound archive and restore functionality for GitHub issue #1403.

Features:
- New MarketState enum values: Archived, Restored
- archive_event(): Transition Resolved/Cancelled → Archived
- restore_event(): Transition Archived → Restored
- Lifecycle validation with corruption detection
- Archive/restore events with replay protection
- 30+ comprehensive test cases

Error Codes:
- CannotArchiveFromState (442): Archive only from Resolved/Cancelled
- CannotRestoreFromState (444): Restore only from Archived
- MarketAlreadyArchived (445): Duplicate archive rejection
- MarketAlreadyRestored (446): Duplicate restore rejection

Design:
- Backward compatible (NO breaking changes)
- Deterministic state transitions
- Authorization enforced (admin-only)
- Idempotency guaranteed
- Atomic operations (no partial updates)
- Event emission for audit trail
- Comprehensive state validation

Testing:
- 30+ test cases covering success, rejection, boundaries, regression
- Authorization verification
- State consistency validation
- Concurrent operation safety

Documentation:
- MIGRATION_GUIDE_LIFECYCLE.md: Migration path and API reference
- LIFECYCLE_INVARIANTS.md: Formal invariant specifications
- IMPLEMENTATION_VALIDATION.md: Complete validation checklist
- IMPLEMENTATION_SUMMARY.md: High-level feature overview

Closes #1403"
