refactor: read tool['arguments'] directly in the JSON completion guard

Browse source 
Restores the pre-existing comment above the guard to its original wording and drops the `buffered` local, so the guard and the parse call both read `tool['arguments']`, the name the rest of the file already uses for that buffer. Behaviour is unchanged: same three conditions in the same order, same short-circuit result.
