chore: Migrate project from pnpm to bun for dependency management and scripts

This commit transitions the project from using pnpm to bun for dependency management and script execution. Key changes include updating installation commands, modifying script definitions in package.json, and adjusting documentation to reflect the new setup. The migration aims to streamline the development process and improve performance. Additionally, the removal of pnpm-related files enhances project clarity and maintainability.
