Streaming Telegram Agent

"""
Streaming Telegram Agent
========================

Telegram bot that streams responses token-by-token, editing the message
in real time so the user sees incremental output instead of waiting for
the full response.

Key concepts:
  - ``streaming=True`` on the Telegram interface enables chunked message edits.
  - Uses OpenAI gpt-4o-mini for fast token generation.
  - SQLite session persistence keeps conversation history across restarts.

Setup: Set TELEGRAM_TOKEN env var from @BotFather.
