"""Shared fixtures for gateway e2e tests (Telegram, Discord).

These tests exercise the full async message flow:
    adapter.handle_message(event)
        → background task
        → GatewayRunner._handle_message (command dispatch)
        → adapter.send() (captured by mock)

No LLM, no real platform connections.
