@clack/prompts implement

[Sumangal44]

This pull request updates the build system and dependency management for the project, transitioning the main entry point to TypeScript and introducing a modern build workflow. The changes enhance maintainability and developer experience by adding new scripts, updating dependencies, and configuring the build process.

Build and Entry Point Updates:

• Changed the CLI entry point in package.json from index.js to the built file ./dist/index.js, and set the main entry to index.ts to support TypeScript-based development.
• Added a new build configuration file tsup.config.ts to use tsup for building the project, targeting ESM output and ES2020 compatibility.

Scripts and Dependency Management:

• Introduced new scripts in package.json for starting, building, formatting, and updating dependencies, streamlining common development tasks.
• Updated and added dependencies in package.json, including switching from prompts to @clack/prompts, adding cross-spawn, and including TypeScript-related dev dependencies. Also updated the pnpm package manager version.
• Added onlyBuiltDependencies configuration to pnpm-workspace.yaml to specify that only esbuild should be built as a dependency, optimizing workspace builds.

Hey, thanks for the PR. However this is a bit difficult for me to review as a lot of changes are made at once. I understand it's a bit cumbersome, but it would be helpful if each changes are made as separates PRs, e.g. TypeScript conversion, @clack/prompts swap, other dependency alignments, etc. This makes it easier for me to maintain the project in the future.
