llm-wiki: init at 0.4.10 [LLM-assisted contribution]

[futile]

DISCLOSURE: THE COMMITS IN THIS PR WERE CREATED WITH LLM-ASSISTANCE.

I did not use any LLM whatsoever to write this PR description.
I have carefully reviewed the LLM output and understand what the new package is doing, and have done my best to make sure it's high-quality.
This includes having looked up things that weren't clear to me, and where necessary improved them and/or left comment(s) to clear up why things are being done.
I have (also using AI) looked up similar packages and existing conventions in this repo to determine the solutions and styles that are most idiomatic in nixpkgs.
I have done this just like I would have if I had written the code myself, or when doing a code review.

Please let me know if I missed something.
I am interested in learning, but this is the first new package I contribute to nixpkgs (I have contributed package updates etc. before), so I might have gotten something wrong.

I fully intend to take responsibility for this new package, and I don't intend to simply pass off reviewer feedback to an LLM or anything like that.

That said, let's move on to actual content of this PR.

Things done

This PR adds a new package, llm-wiki, which packages https://github.com/nashsu/llm_wiki, (mostly) building it from source.

I say "mostly" because the tool originally vendors a binary version of pdfium, which the package replaces with nixpkgs' pdfium-binary, but that is still a binary package (afaiu). That is the only binary part of the build (to the best of my knowledge).

I have only built this on x86_64-linux, but have made sure that it evals on all platforms the tool claims to support and that cargo-tauri.hook also supports.

This PR also adds myself to maintainer-list.nix, since I wasn't on it before.
The commit adding me to that is ordered before (older-than) the commit introducing the new package.

• Built on platform:
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• Tested, as applicable:
  • NixOS tests in nixos/tests.
  • Package tests at passthru.tests.
    • Building the package ran the app's own Rust-/Tauri-based tests
  • Tests in lib/tests or pkgs/test for functions and "core" functionality.
• Ran nixpkgs-review on this PR. See nixpkgs-review usage.
• Tested basic functionality of all binary files, usually in ./result/bin/.
• Nixpkgs Release Notes
  • Package update: when the change is major or breaking.
    • I did not think this change requires release notes, but please let me know if I should include them.
• NixOS Release Notes
  • Module addition: when adding a new NixOS module.
  • Module update: when the change is significant.
• Fits CONTRIBUTING.md, pkgs/README.md, maintainers/README.md and other READMEs.

Since this an LLM-assisted contribution, I looked for guidance/policy around that, and found #514587. Following that (even though it's not yet merged, I thought it best to follow it nevertheless), I added the appropriate Assisted-by: git trailers, and am including the new checkbox that the PR suggests as well:

• Follows the automation/AI policy.

Actually, the app is not that great. While I created this derivation to use it myself, I'm not sure it's actually a good app that I want to be responsible for. And I have no idea if I'll even continue using it, so I'll put this PR into draft-mode for now, so hopefully nobody spends time on this until I decide what I want to do. At the same time, it's here if someone wants/needs it 🤷
