[FEATURE] Open new session in this group

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I'm using the groups sections on Claude Code for Windows to separate the sessions for multiple projects.
When you open a new session it always goes to "Ungrouped" and it's not convenient.

Proposed Solution

I'd like an option to create a new session on a group.
Or if you have a currently selected session that's on a group, the new session should open on the new group, probably at the top of the group so it's easy to see where it is.
