Changelog — v0.2.39-nix

The Nix edition of the v0.2.39 release — the same changes, plus the edition notes below.

• The flake template's animated fastfetch overlay carries the same logo fixes as the setup-launcher build: logos from 1-bit or 16-bit PNGs draw again, and the logo is placed through Unicode placeholders.

Edition notes

• This edition ships for 64-bit devices only — arm64-v8a and x86_64.
• setup-launcher here installs the flake template; packages come from nixpkgs.
