Quitting the Desktop app wrote "[boot] Restarting desktop connection" to
desktop.log and pushed the same message to the renderer over
hermes:boot-progress. Nothing was restarting: the quit coordinator called
teardownPrimaryBackendAndWait() with the default soft=false, and soft=false
is what makes resetHermesConnectionState() call
resetBootProgressForReconnect().
Name the two teardown intents in quit-teardown.ts and use them at every
deliberate primary teardown: a teardown that re-homes ('reconnect', update
hand-off and bundle swap) keeps the announcement; one that brings nothing
back ('quit', the quit coordinator and the uninstall teardown) stays silent.
Fixes#123437.
