What is the problem this feature would solve?

Would be nice that scripts inside package.json override default bun task.

What is the feature you are proposing to solve the problem?

For example, defining the script "build" and "test" would not call bun's default but the defined script content, allowing to define custom behaviors and overriding.

It would ease the integration with other languages where you want to build or test, that it's not meant to be actually building the typescript but doing some custom actions or build something different than the default bun build action.

Hope that make sense :)

What alternatives have you considered?

Simply specifying bun run <script> everytime but less convenient than bun <script> directly.
