"""Unit tests for DingDing adapter fixes.

Tests cover:
  - send_reaction: emoji mapping and API call construction
  - delete_message: correct API URLs and payload format
  - Rate limit semaphore: safe reset without overflow
  - Stream reconnection: reconnect delay and cancellation
  - Token manager: close() cleanup
  - Stream handler: sessionWebhook extraction
