Pup - Puppeteer Bridge

// Adom Pup popup — thin trigger surface. Finds pup's loopback port (cached), resolves which pup
// session owns THIS tab's window, and fires the same /command verbs the taskbar jump lists use,
// with caller identity 'user-toolbar' (ownership-gate exempt on the pup side: USER_CALLERS).
