v0.23.6

Fixed

• Restored reliable auto-compaction for long-lived Claude Agent SDK sessions.
• Claude Threads now checks the SDK's live context telemetry before each user turn and proactively compacts when the projected turn approaches the SDK threshold.
• The user's message waits until compaction finishes, avoiding terminal input-too-long failures while preserving background-task delivery and session continuity.

Verification

• TypeScript typecheck
• 1,230 unit/integration tests
• Production build
• Regression coverage for compact-before-send ordering and hidden maintenance-turn completion
