fix: update Dockerfile for new daemon-backed architecture

  - Remove `serve` subcommand from ENTRYPOINT — `cocoindex-code` with no
    args is the correct invocation under the new architecture; it auto-reads
    env vars, creates settings, and delegates to the internal daemon
  - Copy `ccc` binary into the runtime stage alongside `cocoindex-code`
  - Bump cocoindex floor pin from >=1.0.0a16 to >=1.0.0a33
