ci: add automated deployment status summaries to GitHub Actions

[AnzalKhan16]

📌 Overview

This PR adds automated deployment status summaries to the CI/CD pipeline. It introduces a new deploy.yml GitHub Actions workflow that simulates a deployment and post-deployment health check. Upon completion, the workflow generates a rich Markdown summary table in the GitHub Actions job summary ($GITHUB_STEP_SUMMARY) displaying:

• ✅ Success or ❌ Failure status
• 🌿 The deployed branch or tag
• 🔖 The deployed commit SHA
• ⏱️ Total deployment duration
• 🩺 Health-check results
• ❌ Useful failure details (if applicable)

🛠️ Type of Change

• ⛓️ Smart Contract (Solidity changes, Gas optimization)
• 💻 Frontend (UI/UX, React components, Tailwind)
• ⚙️ Backend (API routes, MongoDB schemas, Middleware)
• 📄 Documentation (README, Roadmap updates)
• 🧪 Testing (Hardhat tests, Jest/Vitest)
• 🤖 CI/CD (GitHub Actions, Automation)

💬 Additional Notes

The current deploy.yml file contains placeholder sleep and echo commands to mock the deployment and health check processes. When ready, you can seamlessly swap these out with the actual deployment commands while keeping the notification logic intact!
