feat(openclaw): support ratio-based commit threshold

[yeyitech]

Summary

• add commitTokenThresholdRatio to the OpenClaw plugin config and manifest
• derive the effective auto-commit threshold from runtime model context window or token budget when ratio is set
• keep fixed commitTokenThreshold as the fallback and document/test the precedence

Testing

• npm test -- tests/ut/config.test.ts tests/ut/context-engine-afterTurn.test.ts
• npm test

Closes #1172

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis ✅ 1172 - Fully compliant Compliant requirements: Added commitTokenThresholdRatio to config and manifest Implemented ratio-based threshold calculation Ratio takes precedence over fixed threshold Ratio clamped to max 0.49 (49%) Extracts context window from runtimeContext (multiple keys/nested paths) Falls back to fixed threshold when ratio is set but no context window/token budget available
