Auto-compact circuit breaker prevents compaction on Haiku (v2.1.65+)

Issue

Auto-compact not triggering on Haiku, allowing context to reach 90%+ without attempting compaction.

Environment

• Model: Haiku 4.5
• Version: v2.1.65
• OS: macOS

Behavior

• Earlier session today: auto-compact worked correctly
• New session opened 40m ago: auto-compact never triggered
• Context reached 90%+ threshold (autoCompactThreshold set to 0.8)
• Never attempted any compaction in this session
• Manual /compact works as expected

Root Cause

Likely circuit breaker issue (v2.1.116+) stopping after 3 failed auto-compact attempts. gsd-context-monitor.js warns about regression since v2.1.62.

Workaround

Manual /compact command restores compaction ability.
