anki: fix darwin build, add missing platform wheels

[tomrfitz]

anki-audio and anki-mac-helper aren't available in python3Packages. uv requires them to build on darwin, but sandboxed builder can't fetch them, so fetch them here and link them alongside other wheels.

This fixes the regression on darwin from #498788 which was missing two darwin-specific, anki-only deps. This is less clean than adding those deps to python3Packages, but since they're only used for anki (afaik) this gets darwin back online more quickly. x86_64-linux build is unaffected in my testing since these wheels are platform gated.

One style comment which I don't feel strongly about at all, feel free to ignore it either way!

I can't test the darwin build since I don't have a macOS device, but the change makes sense to me, thank you!

[dotlambda]

anki-audio and anki-mac-helper aren't available in python3Packages

Add them to python3Packages instead.

[tomrfitz]

Amended and pushed again with your suggested change as i understand it.

test build passed on x86_64-linux and here's nixpkgs-review output:

16 packages built:
anki anki.doc anki.lib anki.man ki ki.dist mnemosyne mnemosyne.dist python313Packages.anki-audio python313Packages.anki-audio.dist python313Packages.anki-mac-helper python313Packages.anki-mac-helper.dist python314Packages.anki-audio python314Packages.anki-audio.dist python314Packages.anki-mac-helper python314Packages.anki-mac-helper.dist

i haven't worked that in depth before in nixpkgs so that was a fun detour to learn how things work in more detail.

[dotlambda]

meta.sourceProvenance missing
separate commits please

[tomrfitz]

Pushed again with the two suggested changes:

• anki-audio: use lib.getExe and ln -s instead of cp
• anki-mac-helper: use "${finalAttrs.src.name}/ ..." instead of "source/ ..."

Open to feedback regarding where to pin anki-mac-helper.
