chore(nix): use mkShellNoCC for lighter dev shell

[ryoppippi]

Switch from mkShell to mkShellNoCC since this project doesn't require a C compiler toolchain. This reduces unnecessary dependencies and speeds up shell initialisation for Node.js/pnpm development.

Also updates flake.lock to latest inputs.
