chore: enable bun isolated install

[ryoppippi]

https://bun.com/docs/pm/isolated-installs
bun introduces isolated installs(similar to pnpm), and it is good for dependency management.

The author should do the following, if applicable

• Add tests
• Run tests
• bun run format:fix && bun run lint:fix to format the code
• Add TSDoc/JSDoc to document the code
