douxu 1b1f43db7f feat: implement topology analysis async task with BFS connectivity check 
- add TopologyAnalysisHandler.Execute() with 5-phase BFS reachability
    check between start/end component UUIDs; support CheckInService flag
    to skip out-of-service nodes during traversal
  - carry task params through RabbitMQ message (TaskQueueMessage.Params)
    instead of re-querying DB in handler; update TaskHandler.Execute
    interface and all handler signatures accordingly
  - fix BuildMultiBranchTree UUIDFrom condition bug; return nodeMap for
    O(1) lookup; add QueryTopologicByStartUUID for directed traversal
  - add QueryBayByUUID/QueryBaysByUUIDs and
    QueryComponentsInServiceByUUIDs (two-column select) to database layer
  - add diagram.FindPath via LCA algorithm for tree path reconstruction
  - move initTracerProvider to middleware.InitTracerProvider; add
    OtelConfig struct to ModelRTConfig for endpoint configuration
  - update topology analysis params to start/end_component_uuid +
    check_in_service; remove dead topology init code

douxu 03bd058558 feat: implement end-to-end distributed tracing for HTTP and async tasks 
- introduce typed traceCtxKey to prevent context key collisions (staticcheck fix)
  - inject B3 trace values into c.Request.Context() in StartTrace middleware
    so handlers using c.Request.Context() carry trace info
  - create startup trace context in main.go, replacing context.TODO()
  - propagate HTTP traceID/spanID through TaskQueueMessage into RabbitMQ
    worker, linking HTTP request → publish → execution on the same traceID
  - fix GORM logger null traceID by binding ctx to AutoMigrate and queries
    via db.WithContext(ctx)
  - thread ctx through handler factory to fix null traceID in startup logs
  - replace per-request RabbitMQ producer with channel-based
    PushTaskToRabbitMQ goroutine; restrict Swagger to non-production

douxu 809e1cd87d Refactor: extract task constants to dedicated constants package 
- Add constants/task.go with centralized task-related constants
    - Task priority levels (default, high, low)
    - Task queue configuration (exchange, queue, routing key)
    - Task message settings (max priority, TTL)
    - Task retry settings (max retries, delays)
    - Test task settings (sleep duration, max limit)

  - Update task-related files to use constants from constants package:
    - handler/async_task_create_handler.go
    - task/queue_message.go
    - task/queue_producer.go
    - task/retry_manager.go
    - task/test_task.go
    - task/types.go (add TypeTest)
    - task/worker.go

douxu 4a3f7a65bc Refactor async task handlers into specialized handlers 
Split monolithic async_task_handler.go into separate handlers:
- async_task_cancel_handler.go: Handles task cancellation
- async_task_create_handler.go: Handles task creation
- async_task_progress_update_handler.go: Handles progress updates
- async_task_result_detail_handler.go: Handles result details
- async_task_result_query_handler.go: Handles result queries
- async_task_status_update_handler.go: Handles status updates

This improves code organization and maintainability by separating concerns.
