Description

Migrate Firestore adapter with Lytics-specific schema to the internal package. This adapter writes test results and runs to Firestore collections for dashboard visualization and trend analysis. It includes retry logic and proper error handling for production reliability.

Acceptance Criteria

• Adapter implements ResultAdapter interface from @lytics/playwright-reporter
• Writes to Firestore collections (test_runs, individual_test_runs, latest_test_cases) correctly
• Handles GCP authentication (Application Default Credentials + Service Account JSON fallback)
• Includes retry logic with exponential backoff for transient failures
• Unit tests pass with Firestore emulator or mocks
• Published to GitHub Packages registry
• Documentation includes authentication setup and Firestore schema

Technical Requirements

• Migrate FirestoreAdapter.ts implementing ResultAdapter interface
• Update imports to use @lytics/playwright-reporter
• Configure publishConfig for GitHub Packages
• Add error handling for network failures and auth issues
• Document Firestore collections schema
• Add examples for local development vs CI environment
