## Status
IMPLEMENTED

## Description
GitHub Code Scanning REST API client is implemented with SARIF upload, processing status polling, alert filtering, and integration with the GitHubApp connector plugin.

## Implementation Details
- **Code scanning client**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/GitHubCodeScanningClient.cs`, `IGitHubCodeScanningClient.cs` -- SARIF upload and alert retrieval
- **SARIF upload request**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/SarifUploadRequest.cs` -- upload payload model
- **SARIF upload result**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/SarifUploadResult.cs` -- upload response model
- **Upload status**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/SarifUploadStatus.cs` -- upload status tracking
- **Processing status**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/ProcessingStatus.cs` -- processing state enum
- **Alert filter**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/AlertFilter.cs` -- alert filtering logic
- **Alert model**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/CodeScanningAlert.cs` -- alert data model
- **DI extensions**: `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/CodeScanning/GitHubCodeScanningExtensions.cs`
- **Tests**: `src/Integrations/__Tests/StellaOps.Integrations.Tests/CodeScanning/GitHubCodeScanningClientTests.cs`
- **Source**: Feature matrix scan

## E2E Test Plan
- [ ] Verify SARIF upload to GitHub Code Scanning API
- [ ] Test processing status polling until upload is complete
- [ ] Verify alert filtering returns relevant alerts
- [ ] Test upload handles large SARIF files (gzip compression)
- [ ] Verify integration with GitHubApp connector plugin authentication
