Implement AI Scanner Timeout & Fallback Strategy

[GauravKarakoti]

• Description: The PR scanning workflow relies entirely on Groq's Llama 3.1 model generating the security report. If the Groq API experiences downtime, rate-limiting, or a timeout on an exceptionally large PR diff, the GitHub Check Run could hang indefinitely in a "Pending" state, blocking developers from merging their code.
• Proposed Solution:
  • Implement a strict timeout wrapper around the LLM invocation in ArmorIQScanner.
  • If the scan times out or the API fails, gracefully catch the error and update the GitHub Check Run status to Neutral or Skipped.
  • Log the failure comprehensively in the AuditLog with the error details in the metadata JSON field.
  • Post a fallback PR comment notifying the developer that the automated security scan could not be completed.
