Detailed Description

Host-owned extension UI, persistence, preferences, console and jobs.

One host instance isolates each plugin's contribution IDs, preferences, network policy client and bounded output channel. Application-specific work is delegated through ExtensionUiBridge callbacks; concrete model access is installed separately.

Document factories remain borrowed while registered. Created widgets transfer to the host, and unknown persisted document kinds remain pending until their factory appears. Model lifetime signals close associated views before their model facade becomes unavailable.

Worker callbacks are marshalled to the GUI thread. Shutdown first suppresses continuations, requests cancellation and joins workers; the manager then calls plugin shutdown. Host destruction removes preferences pages, views, docks, ribbon tabs and actions in dependency order. Native libraries stay pinned, so retained Qt callback code cannot be unloaded.
