Summary

This change restores dark mode as the default appearance and fixes a migration issue affecting users on 3.x and 4.x.

Previously, the migration logic only handled users upgrading from pre-3.0 versions. As a result, users already on 3.x or 4.x could lose their expected appearance setting during migration.

What’s changed

• Restores dark mode (.dark) as the default value for appearanceMode
• Adds a new migration step to correctly handle:
  • Users coming from 3.x and 4.x
  • Legacy forceDarkMode stored via StorageValue
• Ensures appearance is migrated consistently:
  • true → .dark
  • false → .system

Why

• Dark mode was no longer the default
• Migration logic did not cover all upgrade paths, leading to incorrect appearance settings for existing users

Impact

• No behavior change for users with an explicit appearance setting
• Correct and predictable migration for all users, regardless of upgrade path
