Research direction

The issue is about the `parser/known variables` function incorrectly handling variables inside tags like `{% if {{var}} %}`. The fix likely involves adjusting the regex or parsing logic in the `known variables` function to strip the outer `{% %}` tags before extracting variable names. Relevant source files are likely in the parser or template module of the Selmer library. The issue already provides a clear example and expected output, so the fix should be straightforward but requires understanding of Clojure's string manipulation and regex.
