The scheme-service boot path in service.rs used .expect("TODO") on two
boot-critical libredox calls:
- libredox::call::getns() — gets a fd to the current namespace
- libredox::call::register_scheme_to_ns() — registers the spawned
scheme into that namespace
If either call fails the scheme is invisible, which is non-recoverable
for boot. The placeholder "TODO" message gave no diagnostic value.
Replaced with descriptive messages:
- getns: .expect("init: failed to get current namespace fd; ...")
- register_scheme: unwrap_or_else(|e| panic!(...)) including the
scheme name and the error, matching the existing pattern at line 87
(create_pipe unwrap_or_else).
No behaviour change — both paths still panic on failure. The only
difference is that the panic message now identifies the failure and
includes the offending scheme name.
