Subject: [PATCH] Add exhaustive initialization lint to MachineStepResultJson

Annotates `MachineStepResultJson` in validator/server_api/json.go with
`// lint:require-exhaustive-initialization`. The struct has 4 fields
(Hash, Position, Status, GlobalState) and only one initialization site
in this repo (the adjacent MachineStepResultToJson helper), which
already sets all four fields. No initializer changes needed.

Adding the annotation ensures any future addition of a field to this
struct will trip the linter on the existing initializer instead of
silently zero-valuing, which is the goal stated in the issue.

Addresses #3121 following the one-struct-per-PR guidance from the
maintainers in earlier threads.
