GitHub Copilot SDK AIAgent Implementation

All Changes Complete

  • Fixed event handling: Added AgentResponseUpdate yields for SessionIdleEvent and SessionErrorEvent
  • Removed explicit subscription.Dispose() (handled by using statement)
  • Removed AutoStart from README example (defaults to true)
  • Moved name/description defaults to primary constructor (applies to all construction paths)
  • Made Name and Description properties non-nullable (always have defaults)
  • Enhanced UsageContent with complete usage details:
    • InputTokenCount from InputTokens
    • OutputTokenCount from OutputTokens
    • CachedInputTokenCount from CacheReadTokens
    • AdditionalCounts for CacheWriteTokens, Cost, Duration
  • All 11 tests passing across net8.0, net9.0, net10.0
  • All builds successful

Implementation Complete

All PR feedback addressed. Event handling complete, usage tracking comprehensive, defaults properly applied.
