fix: condense 429 error logging and suppress litellm Provider List spam

[b3nw]

two small logging "fixes"/improvements.

Issue 1: Gemini CLI 429 errors were dumping the full JSON error body across 20+ lines of console output. Now extracts key info (message, quotaResetDelay) into a single warning line. Full body still logged to transaction file.

Issue 2: litellm prints 'Provider List: https://docs.litellm.ai/docs/providers' when custom OpenAI-compatible providers aren't in its known model list. Set litellm.suppress_debug_info = True to silence this.

Important

Condense Gemini CLI 429 error logs and suppress litellm provider list log to improve console readability.

• Logging Improvements:
  • Condense Gemini CLI 429 error logs in gemini_cli_provider.py to a single console line with key info (message, quotaResetDelay), while logging full error body to transaction file.
  • Suppress litellm provider list log in main.py by setting litellm.suppress_debug_info = True.
• Behavior:
  • Console output for 429 errors now shows a single-line summary instead of full JSON body.
  • Full error details are still logged to the transaction file for debugging purposes.
