Request: Add release tarballs with submodules included

[Justus2308]

Github sadly doesn't include submodules into tarballs obtained via .../archive/master.tar.gz. This needs to be done manually or using Github Actions and a script like this.

Not being able to download this repo with submodules included (without using git clone --recursive) currently makes it unusable as a 'native' zig dependency as zig build fails with error: failed to check cache: '/Users/.../ext/SPIRV-Tools/source/assembly_grammar.cpp' file_hash FileNotFound.

Having precompiled binaries is already a very good solution but having this feature would make using shdc as a dependency in a zig project even nicer :)

Noted but I need to think about it :D

Somewhat similar I have a similar 'Dear ImGui source distribution' here, but for slightly different reasons:

https://github.com/floooh/dcimgui/

...and whenever there's a new Dear ImGui version I just need to toggle a CI job which creates a new source distro and pushes it to the repository with a version tag.

...this basically bundles the current Dear ImGui sources plus generated C bindings and the same for the docking-branch-sources in a one-in-all repository which is also usable by Zig (and one of the reasons I did this was also because the Zig package manager couldn't handle git submodules)...
