Research direction

Investigate how the plugin currently highlights parameter expansions in command position. Look for the regex or parsing logic that determines command vs path highlighting, likely in the main highlighter file (e.g., highlighters/main/main.zsh). Check if there are any existing test cases for similar patterns. Consider adding a test for '$foo/bar' and modifying the appropriate highlight function.
