build: upgrade nix from 0.27 to 0.29

[morrisonlevi]

PROF-11721

What does this PR do?

This upgrades nix from v0.27 to v0.29. There's an off-by-one error in the new Backlog type, so this lowers the backlog used for listen from 128 to 127.

Also pins simd-json to 0.14. I noticed v0.15 requires Rust 1.85 and I was editing this file anyway.

Motivation

Version 0.29 was already in our tree, so this removes a duplicate dependency (everything is now on 0.29).

Additional Notes

I tried to use Cursor to do this upgrade, and it failed, even when I provided the changelog for versions 0.29 and 0.28. Did it all manually.

How to test the change?

Everything should test the same.

There are test failures in GitLab with the sidecar failing to start. It seems possible that this PR affects it given that it changes some things in IPC and sidecar. I'm waiting on Bob's opinion and investigation into the failures.

[morrisonlevi]

There is a bug in nix 0.29.0: nix-rust/nix#2500. It's been fixed but not released. Work around by lowering backlog from 128 to 127.

Looks good, thanks Levi :-)
