[pr-66] fix: make old_line and new_line optional for image diff discussions

🐛 Bug Fix:
- Image files in GitLab MR discussions use x/y coordinates instead of line numbers
- Fixed schema validation error when fetching discussions on image files

📝 Details:
- Changed old_line and new_line from required to optional in GitLabDiscussionNoteSchema
- Allows proper handling of image diff comments that use position_type: 'image'

+# PR Validation Guide
+
+## Overview
+
+All Pull Requests are now automatically tested and validated. Manual testing is no longer required!
+
+## Automated Validation Items
+
+### 1. Build and Type Check
+
+- TypeScript compilation success
+- No type errors
+
+### 2. Testing
+
+- **Unit Tests**: API endpoints, error handling, authentication, etc.
+- **Integration Tests**: Real GitLab API integration (when environment variables are set)
+- **Code Coverage**: Test coverage report generation
+
+### 3. Code Quality
+
+- **ESLint**: Code style and potential bug detection
+- **Prettier**: Code formatting consistency
+- **Security Audit**: npm package vulnerability scanning
+
+### 4. Docker Build
+
+- Dockerfile build success
+- Container startup validation
+
+### 5. Node.js Version Compatibility
+
+- Tested across Node.js 18.x, 20.x, and 22.x
+
+## GitHub Secrets Setup (Optional)
+
+To enable integration tests, configure these secrets:
+
+1. `GITLAB_TOKEN_TEST`: GitLab Personal Access Token
+2. `TEST_PROJECT_ID`: Test GitLab project ID
+3. `GITLAB_API_URL`: GitLab API URL (default: https://gitlab.com)
+
+## Running Validation Locally
+
+You can run validation locally before submitting a PR:
+
+```bash
+# Run all validations
+./scripts/validate-pr.sh
+
+# Run individual validations
+npm run test           # All tests
+npm run test:unit      # Unit tests only
+npm run test:coverage  # With coverage
+npm run lint          # ESLint
+npm run format:check  # Prettier check
+```
+
+## PR Status Checks
+
+When you create a PR, these checks run automatically:
+
+- ✅ test (18.x)
+- ✅ test (20.x)
+- ✅ test (22.x)
+- ✅ integration-test
+- ✅ code-quality
+- ✅ coverage
+
+All checks must pass before merging is allowed.
+
+## Troubleshooting
+
+### Test Failures
+
+1. Check the failed test in the PR's "Checks" tab
+2. Review specific error messages in the logs
+3. Run the test locally to debug
+
+### Formatting Errors
+
+```bash
+npm run format      # Auto-fix formatting
+npm run lint:fix    # Auto-fix ESLint issues
+```
+
+### Type Errors
+
+```bash
+npx tsc --noEmit    # Run type check only
+```
+
+## Dependabot Auto-merge
+
+- Minor and patch updates are automatically merged
+- Major updates require manual review

+# GitHub Secrets Setup Guide
+
+## 1. Navigate to GitHub Repository
+
+1. Go to your `gitlab-mcp` repository on GitHub
+2. Click on the Settings tab
+3. In the left sidebar, select "Secrets and variables" → "Actions"
+
+## 2. Add Secrets
+
+Click the "New repository secret" button and add the following secrets:
+
+### GITLAB_TOKEN_TEST
+
+- **Name**: `GITLAB_TOKEN_TEST`
+- **Value**: Your GitLab Personal Access Token
+- Used for integration tests to call the real GitLab API
+
+### TEST_PROJECT_ID
+
+- **Name**: `TEST_PROJECT_ID`
+- **Value**: Your test project ID (e.g., `70322092`)
+- The GitLab project ID used for testing
+
+### GITLAB_API_URL (Optional)
+
+- **Name**: `GITLAB_API_URL`
+- **Value**: `https://gitlab.com`
+- Only set this if using a different GitLab instance (default is https://gitlab.com)
+
+## 3. Verify Configuration
+
+To verify your secrets are properly configured:
+
+1. Create a PR or update an existing PR
+2. Check the workflow execution in the Actions tab
+3. Confirm that the "integration-test" job successfully calls the GitLab API
+
+## Security Best Practices
+
+- Never commit GitLab tokens directly in code
+- Grant minimal required permissions to tokens (read_api, write_repository)
+- Rotate tokens regularly
+
+## Local Testing
+
+To run integration tests locally:
+
+```bash
+export GITLAB_TOKEN_TEST="your-token-here"
+export TEST_PROJECT_ID="70322092"
+export GITLAB_API_URL="https://gitlab.com"
+
+npm run test:integration
+```
+
+⚠️ **Important**: When testing locally, use environment variables and never commit tokens to the repository!
