[Bug] Compaction fails with "Conversation too long" error despite available context

Bug Description
the following issue makes no sense in terms of productivity. That bring very sad sentiment about claude, no choice but to use other tool for now:
⏺ Background command "Run full make pipeline to validate refactored code" completed (exit code 0).
⎿  Context low · Run /compact to compact & continue

/compact

⎿  Error: Error during compaction: Error: Conversation too long. Press esc twice to go up a few messages and try again.
