…loses VeriNode-Labs#76) Add src/job_scheduler/mod.rs implementing a priority-queue job scheduler with exclusive lease-based worker claiming: - Workers acquire jobs by priority, holding time-bound leases - Lease renewal prevents expiry while a worker processes a job - Expired leases auto-release jobs back to the pending queue - Max acquisition attempts guard before dead-lettering - Comprehensive test suite (17 tests) covering: - Enqueue/acquire/complete lifecycle - Lease expiry and re-queuing - Worker ownership enforcement - Priority ordering - Capacity limits - Metrics export for monitoring dashboards
Both src/config_audit.rs and src/replication/mod.rs already existed but were never declarated as pub mod in lib.rs, causing unresolved import errors in tests/config_audit_test.rs and tests/replication_dr_test.rs.
