feat: add Kit landing page at kit.pivoine.art

Added kit-ui landing page as the main entry point for the toolkit:
- Image: ghcr.io/valknarness/kit-ui:latest
- URL: https://kit.pivoine.art
- Provides links to Vert (file converter) and Paint (image editor)

Changes:
- Added landing service to kit/compose.yaml
- Updated arty.yml with KIT_TRAEFIK_HOST and KIT_LANDING_IMAGE
- Updated CLAUDE.md with landing page documentation
- Updated README.md with landing page reference

Toolkit structure:
- Landing: kit.pivoine.art (main hub)
- Vert: vert.kit.pivoine.art (file converter)
- Paint: paint.kit.pivoine.art (image editor)
