✨ Add opt-in radial menu movement across displays

[kasyan1337]

Description

Adds an opt-in setting, Move radial menu across screens, for multi-display setups.

When enabled, Loop now:

• Detects when the cursor enters another display while the radial menu is active.
• Repositions the menu at the cursor on the destination display.
• Rebases the radial interaction so direction selection starts from the new display.
• Updates the resize/action target screen to match the cursor destination.
• Preserves the existing behavior by default and respects the radial-menu center-lock option.

The setting includes a tooltip and localized string entries. The default is off to avoid changing existing users’ behavior.

How has this been tested?

• xcodebuild build -project Loop.xcodeproj -scheme Loop -configuration Debug -sdk macosx -derivedDataPath /private/tmp/Loop-DerivedData-pr -clonedSourcePackagesDirPath /private/tmp/Loop-Sources CODE_SIGNING_ALLOWED=NO -skipMacroValidation
  • Passed with Xcode 26.6 on macOS.
• git diff --cached --check
  • Passed before commit.
• The app was launched locally from Xcode after configuring all three local targets with Sign to Run Locally.
• The two-physical-display interaction should be acceptance-tested by the maintainer or contributor on a multi-monitor Mac; this environment did not provide a reliable automated two-display fixture.
• SwiftFormat lint was not run because swiftformat is not installed in the local environment.

The local signing workaround was not included in this PR.
