fx alone handles SIGINT and SIGTERM; the server's own handler, which only cancelled a context that fx's stop did not wait for, is gone. fx's Run exits with the shutdown's code: the one a shutdown request carries, 0 for a signal, 1 when the app fails to start or stop. A listen error asks fx to shut down with exit code 1. A Sentry DSN that cannot be used fails the server's start hook, so fx stops what had already started. The server's stop hook stops the HTTP server, then waits for the images still being processed, both within ShutdownTimeout; images still being processed after that are logged and fail the stop, so the exit code is 1.
