Copy SKILL.md plus optional references/ and templates/.

• Helps refactor view/controller logic into a small ViewModel.
• Keeps ViewModels UI-framework agnostic (no SwiftUI/UIKit/AppKit imports).
• Uses protocol adapters for platform actions (e.g., NSWorkspace reveal).
• Splits state into nested structs to reduce ViewModel sprawl.
• Extracts pure logic into structs/functions first.
• Extracts side-effects controllers/services next (still testable via protocols).
• Adds cancellation, DI, and Swift Testing examples.
