Mechanical `gofmt -w ./internal ./cmd`. Mostly struct-field realignment that had drifted, plus a few trailing-newline fixes. No behaviour change — gofmt is semantics-preserving, and build/vet/test are green either side. Split out from the code-review fixes that follow so those stay reviewable instead of hiding inside a wall of realignment.
