* Tests/Manual/*/Info.plist: Set CPDefaultTheme to Aristo3 across all manual test applications, including those previously overriding to Aristo2.
* Tests/Manual/*/Jakefile: Add an orchestration task to update CPDefaultTheme (e.g., npx jake theme "Aristo3 Dark"). For testing convenience.
* Tests/Manual/*/Jakefile (Narwhal format): Migrate module imports and execution calls to Node equivalents from the capp application template, and remove syntax artifacts.
