Lets PHPantom serve Twig templates and YAML and XML configuration files, as the VS Code extension already does. PHPantom answers completion, go to definition, references and rename for the names a PHP project writes in those files: Symfony and Drupal services, routes, templates and translation keys.

• Added, not replacing. The files keep their language, and the Twig, YAML and XML extensions keep serving them.
• Opt-in. The three languages are listed in opt_in_languages, so PHPantom never starts for them unless a user enables it, and a project without PHP is unaffected. Zed versions before 1.24 ignore that key.

To enable it, add PHPantom to the language, ideally in a PHP project's .zed/settings.json:

{
  "languages": {
    "YAML": { "language_servers": ["phpantom", "..."] },
    "Twig": { "language_servers": ["phpantom", "..."] }
  }
}

Tested as a dev extension in Zed 1.27 on a Drupal 11 site, with the PHPantom Drupal support from PHPantom-dev/phpantom_lsp#535: go to definition from a routing file to the controller, from a menu link and a Twig path() to the route, and references from a route to its PHP, YAML and Twig uses. Formatting a YAML file still goes to the YAML extension.
