Go CI fails on golangci-lint's gofmt check. Ran gofmt -w against
every file the linter named plus a handful of others that drifted
during the autonomous-fleet work. No semantic changes — alignment
of struct field whitespace and one mis-indented import block.
gofmt -l ./... is now empty; go build + go vet are clean.
