Multiple Telegram Bot Instances

"""
Multiple Telegram Bot Instances
================================

Runs two agents behind a single Telegram bot using URL path prefixes
to route messages. Each agent gets its own webhook endpoint and can
optionally use a separate bot token for full isolation.

Key concepts:
  - ``prefix="/basic"`` and ``prefix="/web-research"`` give each agent its own webhook path.
  - Pass ``token=`` per instance to use separate bot tokens, or omit to share one.
  - Both agents share the same AgentOS server and SQLite database.

Setup: Set TELEGRAM_TOKEN env var from @BotFather.
