[FEATURE] Add folder/group organization for sessions in the session list panel

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

Description:

Currently, Claude Code sessions are displayed as a flat list with no way to group or organize them. As the number of sessions grows, it becomes difficult to navigate and find related sessions quickly.

Requested Feature:

Allow users to create named folders/groups in the session list panel and move sessions into them — similar to how browser bookmarks or VS Code workspace folders work.

Use Case:

When working across multiple projects or topics (e.g., MCP integration, UI fixes, grant master agent), sessions pile up in a single flat list. Grouping them by topic, project, or sprint would make navigation significantly faster.

Proposed Solution

Proposed Behavior:

Right-click on the session list → "New Folder"
Drag sessions into folders, or right-click a session → "Move to Folder"
Folders are collapsible
Folders persist across VS Code restarts
Search/filter still works across all sessions inside folders
Workaround currently used:

Prefixing session names (e.g., grants/MCP issue) and using the search box — but this is manual and fragile.

Environment:

Claude Code VS Code Extension
Session list sidebar panel
