Subject: [PATCH] feat(contracts): Add JobCreatedEvent and comprehensive test
 suites

- Add JobCreatedEvent emission to JobRegistry.post_job() for off-chain indexing
- Add 17 comprehensive tests for Escrow Deposit & Milestone Release (>90% coverage)
- Add 15 comprehensive tests for Escrow Dispute & Resolution (>90% coverage)
- Add 10 comprehensive tests for Job Registry Full Lifecycle (>90% coverage)
- All 72 tests pass successfully (37 escrow + 30 job_registry + 5 reputation)
- Enhanced error handling and state validation across all contracts
- Events emitted for all critical state transitions for auditability
