This pull request will merge in the code developed to support the 3D extensions developed for Presentation 4 specification.
Discussed at the August 26 2025 call of the IIIF-Commons group, call minutes at Running Notes
Some notes on the state of this PR -- All of the new code related to 3D content are included, as well as all of the tests. -- As we discussed Aug 26, none of the additional workflow/actions developed in the 3D repository are included, in particular in this PR the documentation will continue to be generated manually. -- The dependency on the module prettier-check has been removed, in response to "severe" security warnings now issued by npm upon install. -- neither the docs nor the package-lock.json changes are included in the commit of this PR -- the package naming, website, and GitHub repo are all set to the IIIF-Commons/manifesto values. -- the version number is unchanged, is at 4.2.22, we agreed that if/when merge is is performed the version would be bumped to the next minor release
