Fix Claude Discord bot frequent reconnection issue

- Add 30-second timeout to all Claude API calls using asyncio.wait_for()
- Improve error handling with proper TimeoutError catching
- Ensure typing task is cancelled in all error scenarios
- Reduce max_tokens from 3000/2500 to 2000 for consistency
- Add explicit return statements to prevent continued execution

This should resolve the >1000 connection issue reported by Discord.
