Tests that exercise error paths in errLog/warn were causing
GitHub Actions to annotate test output with 'Error: R] ...'
(GHA eats '[ERRO' from '[ERROR]' lines and surfaces the rest as
workflow errors), making real failures hard to distinguish from
expected behavior.
- issues.go: route logIssue output through issueLogWriter (io.Writer,
defaults to os.Stdout). errorCount/issues/notices recording is
unchanged so tests still assert via errorCount.
- testmain_test.go: TestMain sets issueLogWriter = io.Discard for
the whole test binary.
- issues_test.go: TestIssuesLogging temporarily redirects
issueLogWriter to a bytes.Buffer (replacing os.Pipe stdout
capture).
go test -v ./... now contains zero stray '[ERROR]' lines; real
test failures remain visible and 'go test' still exits non-zero
on failure, failing the workflow.
