  Error Handling for Model Providers

  Graceful error handling when model provider calls fail.

  Features:

  • Try/catch around provider API calls
  • Error messages persisted as assistant messages
  • Provider metadata tracked on failures
  • Latency captured for all requests (success/failure)

  Exception Types:

  • ModelProviderException - Provider errors
  • RequestTimeoutException - Timeout foundation

  Behavior:

  • User message always saved first
  • Error message: '⚠️ Model provider error: [details]'
  • Full context preserved (provider ID, model, latency)
  • Exception propagated for API error responses

  Future:

  • Per-provider timeout configuration
  • Retry with exponential backoff
  • Fallback provider chains
  • Circuit breaker pattern

  Part of v1.4.0 Chat Runtime milestone (step 6/7).
