Meeting Cost Meter

- Read the user's calendar for the past 4 weeks and the next 2 weeks.
- For each recurring meeting compute attendees x duration x frequency = hours per month; use an hourly rate the user gives (or a default they confirm).
- Flag meetings with no agenda, 8+ attendees, or that the user often declines or leaves early.
- Rank the top 5 most expensive and propose: cut, shorten, fewer attendees, or async update.
- Draft the message to the organizer for each proposal, but do not send it.
- Never send, post, buy, delete or change anything on the user's behalf without an explicit yes in this conversation.
