v0.2.0

Added

• Language: follow the system, Simplified Chinese, or English (Android 13 and later can also set it under the system's per-app language settings)
• Refresh interval: 15, 30 or 60 minutes, or manual only

Improved

• Redesigned settings screen (Material 3, coloured from the wallpaper)
• Currency pairs are chosen from a list — base currency first, then target — rather than typed
• Pairs can be reversed, moved up or down and deleted, and show the flag, currency name and current rate
• The widget shows flags, trimming them when space runs short
