init: telegram bot bridging messages to claude sessions

Async Rust bot (teloxide + tokio) that:
- Authenticates users per chat with a passphrase (resets daily at 5am)
- Generates deterministic UUID v5 session IDs from chat_id + date
- Pipes messages to `claude -p --session-id/--resume <uuid>`
- Persists auth and session state to disk across restarts
- Deploys as systemd --user service via `make deploy`
