feat(ci): add lint and type check GitHub Action

[rahul810050]

Description

This PR adds a GitHub Actions workflow that automatically runs linting and TypeScript checks on every pull request to ensure code quality and prevent type errors.

Changes Made

• Created .github/workflows/ci.yml with lint and type-check workflow
• Workflow runs ESLint, TypeScript compiler, and Prettier checks
• Configured to run on PRs to master and dev branches
• Added npm dependency caching for faster execution
• Set up Node.js 18 (matching project requirements)

Why This is Needed

Without automated checks, code quality issues and type errors can slip into the codebase. This workflow ensures:

• Consistent code style across the project
• No TypeScript errors are introduced
• All code meets the project's quality standards

Testing Done

• Verified workflow runs on PR creation
• Tested with intentional lint errors to ensure failure
• Tested with intentional type errors to ensure failure
• Confirmed successful run with clean code

• I have tested the workflow locally using act
• Documentation has been updated if needed
