+//! Job Management API Handlers
+//!
+//! Implements REST endpoints for job management operations:
+//! - GET /api/v1/jobs - List all jobs
+//! - GET /api/v1/jobs/{id} - Get job status/details
+//! - POST /api/v1/jobs/{id}/rollback - Rollback failed job
+//! - DELETE /api/v1/jobs/{id} - Clear completed job from history
