FB15943245: Focus Filters (SetFocusFilterIntent) should run on app launch too to set initial state

Description

Lets say I have a focus filter like this:

struct FocusFilterIntent: SetFocusFilterIntent {
	static let title: LocalizedStringResource = "Pause Unicorn Mode"

	static let description = IntentDescription("Pause unicorn mode.")

	let displayRepresentation: DisplayRepresentation = "App"

	@Parameter(
		title: "Pause Unicorn Mode",
		default: false
	)
	var isUnicornModePaused: Bool

	@MainActor
	func perform() async throws -> some IntentResult {
		AppState.shared.isUnicornModePaused = isUnicornModePaused
		return .result()
	}
}

// ...

@Observable
final class AppState {
	var isUnicornModePaused = false
}

AppState.shared.isUnicornModePaused will be set when the user has enabled it for a focus and that focus mode is enabled. The problem is that it needs to be set at app launch too, in case the user has the focus mode already enabled.

I think FocusFilterIntent should be run at app launch automatically, so it will set the correct initial state.

I'm aware I could do AppState.shared.isUnicornModePaused = try await FocusFilterIntent.current.isUnicornModePaused at app launch, but I think it would be better if focus filters just worked. This way also does not work if some synchronous initialization state needs to know about isUnicornModePaused as it's initialized asynchronously.
