ci: add GitHub Actions workflow for automated testing

[uvenkatateja]

Adds CI workflow to automatically build and typecheck on every PR.

What's Added

• .github/workflows/ci.yml - Runs build and typecheck on PRs
• CI badge in README

Why

Currently no automated checks. This prevents broken code from being merged.

What it checks

• ✅ All packages build successfully
• ✅ No TypeScript errors
• ✅ Runs on every PR and push to main

Follows standard patterns from Turborepo and pnpm monorepos.

@rohanprasadofficial this adds a CI workflow to automatically run build and typecheck checks, please review when convenient.

Will be checking soon, I am thinking more on it, right now there is now CI that runs after the merge of the PR, I need consolidate on the CICD for the package updates as well.

Thanks for the update! That makes sense happy to align this with the broader CI/CD approach you’re planning.
