Apply squircle mask to Dock icon

[kodjima33]

Summary

• NSApp.applicationIconImage renders raw images without macOS auto-masking, causing the icon to appear as a white square in the Dock
• Apply squircle mask in Swift with 6% margin on each side to match standard macOS Dock icon sizing
• Corner radius matches macOS continuous corners (~22.37%)

Test plan

• Verified icon appears as proper squircle in Dock, matching size of other app icons
• Tested with Omi Dev build locally
