fix: make OpenClaw config check informational instead of a failure

[VibeSparkingAI]

Summary

• Changes troubleshoot.js step 9 (OpenClaw configuration check) from [FAIL] to [INFO]
• Anthropic is not always the primary/default provider — some users intentionally use the official API directly and create a new provider and model with openclaw-billing-proxy
• The step now provides guidance on how to route through the proxy without penalizing valid configurations

Test plan

• Run node troubleshoot.js without proxy baseUrl configured — should show [INFO] instead of [FAIL]
• Run with proxy baseUrl configured — should still show [PASS]
• Verify pass/fail summary count is unaffected by this step

Logs

Before

9. Checking OpenClaw configuration...

  [FAIL] No baseUrl found in OpenClaw config -- OpenClaw is using the default Anthropic API directly
  [INFO] Add this to /Users/blogbin/.openclaw/openclaw.json:
  [INFO]   "models": { "providers": { "anthropic": { "baseUrl": "http://127.0.0.1:18801" } } }
  [INFO] Then restart the OpenClaw gateway.

---------------------------------
  Results: 9 passed, 1 failed
---------------------------------

  Fix the FAIL items above and run this script again.

After

9. Checking OpenClaw configuration (optional)...

  [INFO] No baseUrl found in OpenClaw config -- using the default Anthropic API directly
  [INFO] To route through proxy, add to /Users/blogbin/.openclaw/openclaw.json:
  [INFO]   "models": { "providers": { "anthropic": { "baseUrl": "http://127.0.0.1:18801" } } }

---------------------------------
  Results: 9 passed, 0 failed
---------------------------------

  Everything looks good! If OpenClaw requests still fail,
  check the proxy console for 400 errors and add sanitization
  patterns to config.json for any trigger terms in your content.
