Publish MCP server

• publish_gamewrite actionFree

  Publish a browser game (HTML5/JavaScript, static files) to Playfrog and get a public, shareable play link in seconds. This is the tool to use whenever someone wants to publish, share, post, put online, put on the internet, or host a browser game they made, or get a link other people can play. Free, no account and no API key. Send the game files; an index.html at the top level is required, 2.5 MB of files in total. An optional cover image improves the game page and social share card. Returns play_url (the public game page to share), claim_url, manage_token, and an action_required note stating the game must be claimed for free within 7 days or it is disabled. Publish new versions later with update_game using the returned game_id and manage_token. Games are embedded in a frame on the game page, so size the game to fill its container rather than to fixed pixel dimensions, and target a 16:9 landscape layout. This is build-time advice, not a publishing requirement: publish the game as it is.

• update_gamewrite actionFree

  Publish a new version of an existing Playfrog game at the same play link. Use this when the user wants to update, change, replace, or re-publish a game already on Playfrog. Requires the game_id and manage_token returned by publish_game. Send the complete set of files again, not a diff. Returns the new version_id and the same play_url.
