v3.5

[elalish]

A huge thank you to all our new contributors - so much has happened in this release! And a special shoutout to @zmerlynn for a huge amount of work, including a whole new progress and cancellation API. @AnshulPatil2005 has now pushed Manifold to be double-precision deterministic across architectures. There's also been lot of UX improvement in ManifoldCAD, largely thanks to @swaparup36.

@pca006132 Argh, will we ever get a release to publish all the packages correctly the first time? Somehow npm is trying to publish as 3.4.1 again even though I searched and that string doesn't exist in our repo anymore. Do you have any idea how it could be getting the wrong one?

[zmerlynn]

Claude theory: the repo itself is fine - bindings/wasm/package.json is 3.5.0 in master. But publish_npm.yml downloads the latest completed wasm artifact into ./bindings/wasm/, and that artifact is the entire dir - so its package.json overwrites the checked-out 3.5.0 one. If the release was triggered before the post-#1730 master build finished, the artifact still had 3.4.1, and that's what npm publish saw.

Fix would be narrowing the wasm artifact to just build outputs (not the whole bindings/wasm/ tree), or having publish_npm not clobber package.json from it.

[elalish]

Sure enough, on a rerun it worked, so sounds like Claude knows. Narrowing the wasm artifact sounds like a good idea.
