[Bug] Compacting Fails Repeatedly with Incorrect "Conversation Too Long" Error

Bug Description
Compacting fails over and over again even far before any warning appears. The error then is "Conversation too long" while in fact it's not too long. Ending Claude code, restarting with with --continue and then compacting worked for me in 100% of the cases i tried this since i found out it works.
