Backend:
- Added color (hex) and icon (lucide name) columns to folders and tags
- Default folders seeded with colors: Home=green, Work=indigo, Travel=blue, etc.
- API returns color/icon in sidebar and CRUD responses
- Create/update endpoints accept color and icon
Frontend:
- Mobile: horizontal scrollable pill tabs with colored dots
- Desktop sidebar: colored dots next to folder names
- Active pill gets tinted border matching folder color

Backend:
- New Folder/Tag/ItemTag models with proper relational tables
- Taxonomy CRUD endpoints: list, create, rename, delete, merge tags
- Sidebar endpoint with folder/tag counts
- AI classification reads live folders/tags from DB, not hardcoded
- Default folders/tags seeded on first request per user
- folder_id FK on items for relational integrity
Frontend:
- Left sidebar with Folders/Tags tabs (like Karakeep)
- Click folder/tag to filter items
- "Manage" mode: add new folders/tags, delete existing
- Counts next to each folder/tag
- "All items" option to clear filter
- Replaces the old signal-strip cards
