[Bug] Instant Auto-Compact increases token consumption even when disabled

[BnnQ]

Bug Description after 2.0.64 update (probably because of instant auto-compact introduced) token usage spiked crazy, even though I have auto-compaction disabled. Previously it was only consuming tokens during compaction itself (and much less), but now even without doing anything with the compaction (explicitly), "background" token consumption during claude work is much higher (while running compaction itself no longer consumes tokens, but still). And the more the context is filled, the more tokens are consumed, sometimes I notice how 10% of the 5-hour limit is suddenly eaten up while claude was just doing its regular work at ~180K context. Next message? Another 5-10% eaten. And it definitely wasn't the case previously, it was absolutely possible that 5-10% of 5-hour limit would be eaten within one "message", but progressively, not all of a sudden.

Could be a duplicate of #13551, but others are unrelated since my ticket is specifically about 2.0.64. Previous versions worked fine for me
