'{file_name}' is not a supported file in a language director

Error message

'{file_name}' is not a supported file in a language directory and should be removed

What it means

A generic validation error from `extension test languages`: a file was found in the language directory that is neither a recognized configuration file nor a supported query file name. Zed only accepts known QueryFile names (such as highlights.scm, injections.scm, brackets.scm, etc.) plus language config files; anything else is rejected and the author is told to remove it.

Solutions

1. Remove the unsupported file from the language directory or move it elsewhere in the extension
2. Rename the file to a supported query file name if it was meant to be a tree-sitter query (e.g. highlights.scm, indents.scm, outline.scm)
3. Consult the Zed extension documentation for the list of files allowed in a language directory
