Merge main into feat/pi-extension

With prime-agent-extension-status.patch in place the tray renders
ctx.ui.setStatus() next to the model name, which is what a status line should
be. The widget was a workaround for its absence and was never a substitute:
widgetContainerBelow sits in the fullscreen *scroll* list, not the dock, so it
scrolled away with the transcript, and with both set the project name appeared
twice.

The startup retries stay: resetExtensionUI() clears extension statuses just as
it cleared widgets, so the value set during session_start is still wiped before
it can be seen.
