Closing the main window hides it on macOS and Windows; the page and the
Host keep running and the next show resumes the same document. Windows
gets a permanent tray icon (open / quit) and a one-time notification the
first time the window is hidden after installation.
Every ordinary quit entry asks the Host over a new quit-inspection IPC
request for active tasks (same rule as the update restart check) and
armed scheduled reminders (schedule family of workspace/session-activity
for loaded sessions). Nothing to interrupt quits silently; otherwise a
native message box explains what stops, with Quit as the default and
Cancel on Esc. Inspection failure or a missed two-second deadline counts
as running tasks. The installer restart, fatal recovery, the development
restart command, and OS session end skip the confirmation.
Also: defer the downloaded-update confirmation while the window is hidden,
render the tray ICO from the vector icon, and point the installer's
running-application message at the tray.
Closes#4013
A Host startup failure reached the crash report as a fresh Error built from
a message string three hops away from the original: the Host sent only
error.message over the fatal IPC event, DesktopHostProcess wrapped it in a
new Error, desktopErrorState flattened it to text, and main.ts wrapped that
text again. Stack, cause, code, and path were gone, and the Host's stderr
tail arriving with the later exit was blocked by the first-failure latch.
The Host now sends its complete inspected error alongside the message
(bounded to 64 KiB; carried over IPC rather than stderr because the two
race and the shell reports the first failure it sees). DesktopHostProcess
keeps it on DesktopHostFatalError.diagnostic, the backend error state
carries the original failure object, main.ts reports that object, and the
crash report prints the Host diagnostic verbatim in its own section.
