Regenerate the social/OG card (200+ tools, Private file processing, self-hosted infrastructure) and sync to landing/web/docs; update banner, press kit, package + OpenAPI + Docker Hub descriptions, a leaked docs count, and the English About string.
Add a workflow that publishes DOCKERHUB.md as the snapotter/snapotter repository overview on Docker Hub, on pushes to main that touch DOCKERHUB.md and via manual dispatch. Commit DOCKERHUB.md (previously gitignored) so CI can read it, and refresh its tool counts to 240 to match the README. Auth uses the DOCKER_HUB_README secret (Docker Hub account password) and the existing DOCKERHUB_USERNAME.
