fix(desktop): status bar right-click keeps its own menu (Fixes #89953)

[aydnOktay]

Summary

• Right-clicking the desktop status bar always opened the window-verbs fallback, so Show in status bar (and the context meter) was unreachable.
• Radix asChild Slot lets the child's data-slot win. The footer is data-slot=statusbar, so the coordinator's [data-slot=context-menu-trigger] guard never matched and stopPropagation ate the Radix menu.
• Stamp a dedicated data-hermes-context-menu-trigger on ContextMenuTrigger (after props) and bail on that marker. Any asChild surface with its own data-slot is covered, not just the status bar.

Fixes #89953.

Thanks @aydnOktay — you picked the right layer, and your fix is what ships.

Three PRs landed on #89953 independently, so I consolidated them into #90507. Your two commits are cherry-picked there with authorship intact: the primitive stamps the dedicated marker and the coordinator bails on it, so every asChild surface with its own data-slot is covered rather than just the status bar. The two competing fixes both patched the call site — one exempting data-slot="statusbar" in the coordinator, one renaming the footer's data-slot — and either would have reopened the bug the next time someone wrote an asChild child with its own slot.

One change: I dropped the first of your two tests. It hand-wrote <footer data-slot="statusbar" data-hermes-context-menu-trigger=""> into the DOM and asserted the coordinator honored it, which passes even if ContextMenuTrigger never stamps the marker — the test supplied the attribute itself. Your second test is the one that matters and it stays, paired now with @huklaa's integration test that right-clicks the real status bar against the real coordinator. Both fail with the marker removed.

I also swept the other nine ContextMenuTrigger call sites: the status bar is the only one broken today, and context-menu-trigger is the only Slot-stamped data-slot that any production code uses as a runtime gate, so I left the tooltip/dropdown/dialog triggers alone rather than marking them speculatively.

Superseded by #90507.
