Pull request overview

This PR removes the Bluebird dependency and migrates the codebase (core plugin + packagers + tests) to native Promise and async/await patterns.

Changes:

• Dropped bluebird from package.json and replaced BbPromise.* usages across lib/ and tests/.
• Refactored several modules (notably compilation/packaging paths) to async/await with native concurrency handling.
• Updated Jest mocks/tests to work with Node-style async APIs (fs.readFile, fs.stat) and native promises.

package.json:41

• After removing the bluebird dependency, there are still repo artifacts that reference it (e.g. README.md and examples/babel-webpack-5/lib/App.js import/require bluebird). Consumers following the README or running examples will hit a runtime/module-resolution error unless those references are updated (or bluebird is kept as a dependency/devDependency). Consider updating docs/examples (and regenerating package-lock.json if applicable) as part of this change.

Ah, finally!

Tried exactly this a few years ago, blocked by the support matrix back then. It surely feels weird that this is trivial work now with LLM.
