uv downloads python-build-standalone CPython builds, which are dynamically linked against glibc and expect the standard interpreter at /lib64/ld-linux-x86-64.so.2. On this box that path held the NixOS stub-ld placeholder, so every uv-managed Python failed with exit 127 (e.g. just fediverse-post in cang).

This enables programs.nix-ld in hosts/ai-coding-box/default.nix, replacing the stub with a real glibc loader. The uv Python binary needs only glibc libs (verified by running it directly under the system Nix glibc loader, which worked), so no programs.nix-ld.libraries entries are required. Evaluated with nix build ...toplevel --dry-run: closure picks up nix-ld-2.0.6.

After merge the box needs sudo nixos-rebuild switch --flake .#ai-coding-box to pick it up.

Closes #11
