This pull request updates the project's deployment workflow to use Firebase CLI-generated GitHub Actions for both production and pull request deployments, replacing the previous custom workflow. The changes improve maintainability and align the deployment process with Firebase best practices.

CI/CD Workflow Updates:

• Removed the custom .github/workflows/deploy.yml workflow and replaced it with Firebase CLI-generated workflows for production and pull request deployments. [1] [2] [3]
• Added .github/workflows/firebase-hosting-merge.yml for automated deployments to Firebase Hosting on merges to master.

Configuration Updates:

Build Artifact:
