Adds telegram.close() to finally block to ensure aiohttp session cleanup.
Changes:
- src/main.py:553 - Add await telegram.close() in shutdown
Before:
- broker.close() called ✅
- telegram.close() NOT called ❌
- "Unclosed client session" error on shutdown
After:
- broker.close() called ✅
- telegram.close() called ✅
- Clean shutdown, no resource leak errors
Impact:
- Eliminates aiohttp resource leak warnings
- Proper cleanup of Telegram API connections
- No memory leaks in long-running processes
Related:
- KISBroker.close() already handles broker session
- OverseasBroker reuses KISBroker session (no separate close needed)
- TelegramClient has separate session that needs cleanup
