研究方向

Investigate the highlighting code, likely in the `highlighters/main` directory or similar. The issue highlights trailing garbage like 'foobar' after 'done' in a for loop should be marked as an error (`unknown token`). Look at how existing errors like parse errors are highlighted and extend that logic to cover trailing words after valid commands. Refer to issue #296 for details.
