Unblock build-and-test by fixing C# whitespace violations flagged by dotnet format

[Copilot]

Summary

build-and-test was failing at dotnet format --verify-no-changes --severity warn due to whitespace violations; this PR scopes to formatting-only corrections in the files reported by the failing job so CI can proceed to build/test.

• Failure scope
  • Normalized indentation/whitespace in affected CLI/Core/test files called out by the job log (error WHITESPACE), with no logic/path changes.
• Code-level change shape
  • Kept behavior intact; only structural formatting cleanup to satisfy repository formatting gates.
  • Example (representative):

command.SetAction(async parseResult => {
    var useJson = parseResult.GetValue(SharedCliOptions.JsonOption);
    // ...
});

Boundaries

• Local-first and offline verification remain intact.
• No LMS, IDE-plugin, surveillance, or automatic misconduct scope was added.
• Privacy/security documentation was updated if needed.
• Roadmap and continuity notes were updated if capability changed.

Validation

• dotnet build OWS.sln -nologo
• dotnet test OWS.sln -nologo
• git diff --check
