"""E2E tests for Telegram gateway slash commands.

Each test drives a message through the full async pipeline:
    adapter.handle_message(event)
        → BasePlatformAdapter._process_message_background()
        → GatewayRunner._handle_message() (command dispatch)
        → adapter.send() (captured for assertions)

No LLM involved — only gateway-level commands are tested.
