Visual feedback missing when starting a new session from the sidebar

Summary

When clicking the "new session" command in the left-side panel, there is no visible acknowledgment that the action succeeded. The session does start, but without a loading state, transition, highlight, or toast, the click is indistinguishable from a no-op.

Steps to reproduce

1. Open Claude Code (Windows desktop app).
2. Click the "new session" command in the left panel.
3. Observe: no visible change confirms the action was registered.

Expected behavior

Any user-initiated action should produce immediate visible feedback — e.g. a brief loading indicator, a panel transition, the new session row highlighting, or a toast saying "Session started".

Actual behavior

The click appears to do nothing. The session has in fact begun, but the user has no way to know that without taking a follow-up action (e.g. typing a prompt) to confirm.

Why it matters

Silent success is indistinguishable from failure. Users will either click repeatedly (potentially spawning multiple sessions) or assume the feature is broken and look elsewhere.
