[Bug] /goal command fails with "Prompt is too long" error above 200k tokens when 1M context window disabled

Bug Description
"/goal" fails due to "Prompt is too long" in the Stop hook if you are above 200k tokens and you have the 1m context window disabled (but regular conversation still works just fine up until 1m)
