Add client-side support for Telegram's Managed Bots feature, enabling
zero-copy-paste bot creation during hermes setup:
- New module: hermes_cli/telegram_managed_bot.py
- QR code terminal rendering via qrcode library
- Deep link generation (t.me/newbot/{manager}/{username})
- Pairing protocol client (nonce registration + token polling)
- Full auto-setup orchestrator with animated progress
- Setup wizard (hermes_cli/setup.py)
- Telegram setup now offers Automatic vs Manual choice
- Automatic: scan QR → confirm in Telegram → token saved
- Falls back to manual if auto-setup fails or is declined
- Dependencies: qrcode>=8.0 (pure Python, no PIL needed)
Requires a Nous-hosted manager bot + pairing API (Cloudflare Worker)
to complete the flow. See linked issue for backend infrastructure spec.
