refactor: update build scripts and flake configurations

- Removed `temp_dir` variable and cleaned up build scripts in `justfile`.
- Updated `build-template` to use `mktemp` for temporary directories.
- Added `set -euxo pipefail` to ensure scripts fail on errors.
- Modified `build-darwin`, `build-home-manager`, `build-language`, `build-nixos-desktop`, and `build-nixos-minimal` to use the new `build-template` logic.
- Reordered fields in `template/haskell/flake.nix` for consistency.
- Removed `nodejs` inheritance in `template/vite-react/flake.nix` and cleaned up package definition.
