I want to build a native macOS app named JSONFormatter using Xcode, Swift, and SwiftUI. Use the attached sketch as the visual reference for the application.

Do not write, modify, or generate any code yet.

First, inspect the existing Xcode project and then produce a staged implementation plan. The plan should be detailed enough that each stage can be completed, built, and manually verified before moving to the next stage.

App requirements:

Native macOS SwiftUI application
Two-pane layout

	import Foundation

	enum ImageRequestMode: String, CaseIterable, Identifiable {
	case httpRules
	case cacheFirst
	case reload
	case cacheOnly

	var id: Self { self }

	func loadStatus() {
	projectName = shell("basename \"\(launchDir)\"")
	branch = shell("git -C \"\(launchDir)\" rev-parse --abbrev-ref HEAD 2>/dev/null \|\| echo '(not a git repo)'")
	lastCommit = shell("git -C \"\(launchDir)\" log -1 --pretty=format:'%h %s' 2>/dev/null")
	let raw = shell("git -C \"\(launchDir)\" status --porcelain 2>/dev/null \| wc -l \| tr -d ' '")
	changedFiles = raw.isEmpty ? "–" : raw
	}

	func shell(_ command: String) -> String {
	let task = Process()
	let pipe = Pipe()
	task.standardOutput = pipe
	task.standardError = Pipe()
	task.launchPath = "/bin/bash"
	task.arguments = ["-c", command]
	task.environment = ProcessInfo.processInfo.environment
	try? task.run()
	task.waitUntilExit()

	class AppDelegate: UIResponder, UIApplicationDelegate {
	func application(
	_ application: UIApplication,
	configurationForConnecting connectingSceneSession: UISceneSession,
	options: UIScene.ConnectionOptions
	) -> UISceneConfiguration {
	let configuration = UISceneConfiguration(
	name: "Default Configuration",
	sessionRole: connectingSceneSession.role
	)
