Subject: [PATCH] feat(editor): --info-wcp --json for machine-readable WCP
 metadata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors --info-extract --json and --validate --json. Schema:

  {
    "wcp": "/path/to/zone.wcp",
    "name": "Wj",
    "author": "...",
    "description": "...",
    "version": "1.0",
    "format": "wcp-1.0",
    "mapId": 9000,
    "fileCount": 3,
    "totalBytes": 177671,
    "categories": { "terrain": 2, "data": 1 }
  }

Lets CI scripts inspect packed zones — e.g. fail a release if a
zone's WCP doesn't include a creature category, or auto-tag a
release with the totalBytes field.
