Subject: [PATCH] Add Bun installation checks to Jenkins pipeline

- Introduced a function to ensure Bun is installed on both Unix and Windows environments.
- Updated the Jenkinsfile to call this function during the setup stages, improving the reliability of the build process.
- Ensured the PATH is correctly set for Bun after installation.
