Show description metadata (title, description, keywords) for one or more packages.

Reads each description from the `__ocx.desc` tag in the registry. With multiple packages, JSON output is an object keyed by the requested identifier (`{"<id>": {...}|null}`); plain output prints a header line per package.

`--save-readme` / `--save-logo` write a fixed filename and so require exactly one package.

Usage: ocx package description pull [OPTIONS] <PACKAGE>...

Arguments:
  <PACKAGE>...
          Package repositories to query

Options:
      --save-readme <SAVE_README>
          Save the README to this file or directory (single package only)

      --save-logo <SAVE_LOGO>
          Save the logo to this file or directory (single package only)

  -h, --help
          Print help (see a summary with '-h')
