hotfix: hide launch options when connecting to existing Claude terminal

- Fix primary logic in extension.ts to only show launch options when no terminal exists
- Add hideLaunchOptions() method for explicit control
- Fix race condition in webview initialization to prevent brief appearance of launch options
- Ensure consistent state between extension and provider
- Improve logging for debugging terminal connection scenarios
