Copilot often adds 100+ GB after a swarm of sessions works on tasks.

Copilot often adds 100+ GB after a swarm of sessions works on tasks. While there is a space/manage sessions popup, a couple of pain points.

1. you can select merged sessions as a target for deletion but it doesn't mean the merged sessions aren't working on anything. I'd like to be able to select merged AND idle, and maybe even a time component ex. merged & idle for > 10 min

2. it only loads one page of items and isn't scrollable, you may have to delete archived sessions multiple times

my current workflow is to go to each coordinator and ask them to examine to delete sessions since they have the most context, that could be an option for the manage memory popup to do it in one line instead of manage manually

Start in the /chat path and reproduce the space/manage sessions popup with many archived, merged, and idle sessions. Done should include combined status and time-based selection, access to all sessions through scrolling or pagination, and consideration of a one-line coordinator cleanup action.
