test: extend control-bar test plan with design-mode auto-exit cases

Adds a new section 11b to control-bar-tests-todo.md tracking the
auto-exit behavior wired into the tools panel (app-drawer-button),
Find in Files, Quick Open, and the git toolbar icon — plus future
follow-ups for each (floating variants that would avoid the need
to exit design mode).

+## 11b. Auto-exit design mode from conflicting surfaces

+Each of these invocations must exit design mode before running its
+own behavior. Verify `WorkspaceManager.isInDesignMode()` is `true`
+pre-action, then `false` post-action, and that the feature's UI
+renders on the normal editor chrome (not a blank / broken region).

+- [ ] Git panel gains a floating variant for design mode.
