added automatic version pulling from py toml to the nix flake

[BoxC4T]

found the function to pull from a toml. This should mean the only times that changes to the flake are required would be a change in file struct or dependancys

@BoxC4T Thank you for opening the PR.

I already had this feature in mind. I’ve just been holding off because I want (or need) to keep updating the file manually for a little while longer before automating it. I’ll most likely merge this after the next version bump (v1.4.0.3).

One thing I noticed, both in this PR and PR #360, is that your commit messages aren’t using conventional commit types (e.g. feat, fix, refactor, etc.).

I’d recommend reopening this PR with a properly typed commit message. For example:

• feat: add automatic version pulling from pyproject.toml to flake.nix
• refactor(flake.nix): automatically pull version from pyproject.toml

That way, we can merge it directly from your branch (without needing to squash it) and keep the commit history consistent.
