Update docs, Dockerfile, and CI for container registry support

Expanded documentation in both English and Chinese READMEs to include detailed container registry acceleration usage and deployment instructions. Refactored Dockerfile to use a multi-stage build with workerd for self-hosted deployment. Improved .dockerignore for cleaner builds. Updated GitHub Actions workflows to refine path ignores and metadata extraction. Added config.capnp for workerd configuration. Removed obsolete .html file and enhanced CLAUDE.md with comprehensive architecture and development guidance.
