Release v0.6.0

[munechika-koyo]

Summary

Prepare the v0.6.0 release by merging the current develop branch into the repository's default branch (master).

This release includes:

• IMAS URI/netCDF-aware database entry handling and safer read-mode validation
• GGD grid validity masks, improved 2D geometry calculations, and source-data mapping
• molecular species and profile-loading improvements
• radiation emitter validation and a new 2D radiation notebook
• expanded unit-test coverage and documentation updates

Release impact

This release contains a breaking change: subset values returned by load_grid(..., with_subsets=True) and load_unstruct_grid_2d(..., with_subsets=True) are now (indices, valid_data_mask) tuples.

Versioning remains tag-driven through hatch-vcs. The CHANGELOG.md already contains the 0.6.0 release notes.

Validation

• CI passes
• Documentation build passes
• Wheel and sdist builds pass
• Review the 0.6.0 changelog and add the release date before publishing
• Merge this PR into master
• Create and push tag v0.6.0
• Review and publish the draft GitHub Release generated by the release workflow
• Confirm the PyPI publish workflow succeeds after the GitHub Release is published
