build: replace flake with npins, add Nix packages for web and desktop

- npins pins nixpkgs-unstable + Inter font tarball; shell.nix replaces the flake devshell
- nix/bun-deps.nix: fixed-output bun install of the workspace (hash tied to bun.lock)
- nix/web.nix: static Next.js export; next/font/google patched to local Inter for offline builds
- nix/desktop.nix: tsc-built Electron app embedding the web export, wrapped with nixpkgs electron; ffmpeg-static satisfied by nixpkgs ffmpeg
