nix-config

Nix config for two machines:

• temidaradev: NixOS desktop (x86_64-linux)
• temidaradev-darwin: Apple Silicon Mac (aarch64-darwin), via nix-darwin

Rebuild

nh darwin switch .   # macOS
nh os switch .       # NixOS

Edit hosts/<host>/packages.nix, then rebuild. Mac GUI apps and brews go in darwin/homebrew/default.nix.

Homebrew uses cleanup = "uninstall": anything not in that file gets removed on rebuild. Don't brew install by hand, add it to the file.
