[FEATURE] Desktop app: multi-select to delete or archive multiple sessions at once

Problem Statement

Problem
In the Claude desktop app (Code tab), sessions can only be deleted or archived one at a time. After a few weeks of use I have 30+ sessions, many of them throwaway scratch sessions or duplicates, and cleaning them up takes many repeated clicks and confirmations.

Environment

• Claude desktop app, Code tab, macOS
• ~34 local sessions

Proposed Solution

Proposed solution

• Multi-select in the session sidebar (checkboxes, or Shift/Cmd-click)
• A bulk action bar with "Archive" and "Delete" for the selected sessions
• One confirmation dialog listing the affected sessions
• Optional: "Select all older than N days" or "Select all in this group"

Alternative Solutions

Alternatives considered
Asking Claude to delete sessions through its session-management tool works, but a direct UI option would be faster and doesn't need a model round trip.

Priority

Medium - Would be very helpful
