feat(plugin/telegram_bot): add Telegram bot plugin — remote Pyra chat over Telegram

Runs as a supervised daemon task (asyncio long-polling). Features:
- Sender allowlist + bcrypt passphrase challenge (3 attempts before lockout)
- Rate limiting: 20 messages/hour per user (in-memory, resets on restart)
- Injection scanning on every incoming message (pyra.security.injection)
- Full AI chat with litellm streaming → progressive Telegram message editing
- Tool-use loop (up to 10 iterations) with inline-button approval (120s timeout)
- Conversation history persisted per chat_id in ~/.pyra/telegram_history.db
- Memory context loaded from ~/.pyra/memory/ as system prompt on first message

Vault keys: plugin:telegram_bot:token, allowed_users, passphrase_hash
Deps: python-telegram-bot>=21.0, bcrypt>=4.0.0 (added to telegram + all-plugins extras)

22 new unit tests covering rate limiter, history DB, plugin lifecycle, and auth state.
