Function prepare_in_guest_loader_route_config 

pub fn prepare_in_guest_loader_route_config(config: DetConfig) -> DetConfig

The configuration of an in-guest run on the loader route (the exec-stop, native-exec and mapped-first-admission launchers of hermit run): the in-guest-trap backend’s preparation with site patching off. It keeps today’s behaviour on that route (D13(a), and D26 of the A5 step 3c design: the route’s own comparison gates any change), so the in-guest runtime’s reserved-signal set stays empty here whatever config carried; only the default route sets it (in_guest_reserved_signals).
