If $ARGUMENTS is provided, search meetings for that query - check titles, participants, transcripts, and notes.
If no arguments:
- read
~/Documents/alto-index/granola/index.mdfor the full meeting list - show the most recent meetings with date and title
- highlight any meetings from this week
If the granola folder doesn't exist, tell the user to enable Granola sync in alto.index.
