What is the current behavior?

The project currently uses Yarn for dependency management and CI/CD workflows.

Issue Number: N/A

What is the new behavior?

This PR migrates the entire project from Yarn to pnpm. This includes:

• Local Development Setup: Replaced Yarn-specific files (yarn.lock, .yarn/, .yarnrc.yml) with pnpm equivalents (pnpm-workspace.yaml, .npmrc, pnpm-lock.yaml).
• Package Scripts: Updated package.json scripts across the monorepo (root and individual packages) to use pnpm commands instead of yarn.
• Lerna Configuration: Updated lerna.json to specify pnpm as the npm client.
• TypeScript Configuration: Adjusted tsconfig.build.json files in several packages to correctly exclude dist directories and resolve inter-package dependencies.
• Jest Configuration: Fixed Jest type resolution issues in base and package-specific configurations.
• GitHub CI Workflows: Updated all relevant GitHub Actions workflows (ci.yml, e2e.yml, publish-packages.yml, set-coverage.yml) to use pnpm for installing dependencies, caching, building, linting, and testing.

The migration ensures the project is fully functional with pnpm both locally and in CI/CD.

Does this PR introduce a breaking change?

• Yes
• No

Other information

All build, lint, and test commands have been verified to pass successfully with pnpm.
