Improve conversation excerpt formatting in notes show command

- Added formatConversationExcerpt function to properly unescape JSON strings
- Replaced escaped newlines (\n) with actual newlines for readability
- Unescaped quotes, backslashes, tabs, and other JSON escape sequences
- Tool interactions and conversation context now display with proper formatting
- Much more readable output with proper line breaks and structure

The conversation context is now properly formatted and easy to read instead of being one long escaped string.
