This milestone tracks all development tasks related to stabilizing the new EasyDiffraction API and laying the groundwork for integration with EasyScience components.

The focus is on:

• Finalizing and cleaning the new API
• Improving test coverage and documentation
• Setting up CI workflows and code quality tools
• Planning future work through organized issues and milestones

Linked issues will cover:

• Design and cleanup of the API
• Testing (unit, functional, performance)
• Docstrings and typing
• Integration and structure of calculators
• GitHub workflows and tooling
• General developer experience improvements

Once complete, the API will be frozen and ready for safe extension.
