Plugin screens can report unavailable while a successful catalog request
is still pending. Track the host catalog state so these screens show
progress until their contributions register.
Keep missing surfaces, failed requests, and offline hosts distinct from
loading. Retain existing installed surfaces during catalog refreshes.
Cover pending-to-ready rendering with a real browser regression and
catalog lifecycle tests.
Related to getpaseo/paseo#7088
Keep client plugin installations and local UI state alive through transient host disconnects. Reconcile changed bundles and removals on reconnect and refresh settings changed while offline. Connection switching still replaces the client and reinstalls plugins.
Preserves the implementation from #6731, adds a failing-before/passing-after real browser regression, and corrects the English and Chinese lifecycle documentation. Verified with focused tests, browser reconnect journeys, Android debug offline interaction, root checks and green current-head CI.
