Release v1.9.0

[1.9.0] - 2026-09-15

Added

• Local-first wishlist — wishlists stored in Hive on-device, works offline without auth
• Local-first moodboard — moodboards stored in Hive on-device, no auth required
• SyncService — auto-sync on authentication, manual sync, bidirectional merge
• Manual + Auto sync — toggle in settings, auto-sync on login, pull from cloud to local
• Wallhaven ID storage — wishlists/moodboards use wallhaven_id directly, no FK to wallpapers table

Changed

• WallpaperActions — heart tap works locally without auth, syncs to cloud when authenticated
• AddToMoodboardSheet — reads from Hive, syncs to Supabase when authenticated
• AuthBottomSheet — triggers sync on Google/email sign-in
• WishlistScreen — reads directly from Hive, no Supabase dependency for display

Fixed

• Wishlist 400 error — removed FK constraint dependency, wallpapers no longer need to exist in DB
• Moodboard 400 error — same fix, wallhaven_id stored directly

Schema

• New tables: wishlists_v2, moodboards_v2, moodboard_items_v2 with wallhaven_id VARCHAR(50)
• Data migration from old UUID-based tables preserved in sql/007_local_first.sql
