#448-H: GTK breadcrumb bar non-functional after ShellApp migration (clicks dead / dropdown hidden)

[JDonaghy]

Follow-up to the GTK→ShellApp event-dispatch migration. Parent: #448 (regression from #540). Related: #546, #459. Not a duplicate of #369.

Summary

The breadcrumb bar is non-functional after the migration: clicking a breadcrumb segment does nothing, and its dropdown popup doesn't appear (it may be rendering behind other layers / hidden).

Not a duplicate

• Breadcrumb dropdown: collapsible tree instead of flat file picker #369 is an enhancement (make the breadcrumb dropdown a collapsible tree instead of a flat file picker). This issue is a regression: the existing flat breadcrumb picker stopped working entirely.

Root-cause hint

Breadcrumb hit-testing + popup dispatch on the new click path:

• render::breadcrumb_draw_targets(...) and src/gtk/click.rs:44 (tab-bar/breadcrumb height + routing)
• The dropdown is likely a modal/popup element that isn't wired into the migrated dispatch — possibly the same rendering/dismissal gap tracked in ShellApp: migrate dialog + context-menu rendering and dismissal (right-click & tab-close broken) #546 (dialog + context-menu rendering & dismissal) and Migrate context menu dispatch to ModalStack (platform-neutral) #459 (context-menu → ModalStack). Confirm whether the breadcrumb popup is a ModalStack element not yet hosted on the ShellApp path.

Acceptance

Clicking a breadcrumb segment opens its dropdown and selecting an entry navigates. Add a black-box test asserting the popup appears and a selection dispatches.
