Optimize Compact Operation Cost and Add User Control for Memory Management

Question

**Bug Description**
The compact operation is really expensive (monetarily speaking) and offers little value over simply quiting and restarting claude. You should at least give the user a choice to compact or simply quit instead of doing it automatically, it's especially painful when the request is something small but triggers a full compact costing like $2 in API use to change a single line of code. An option to abort and restart would be very welcome.
