feat: Move bootstrap/build-liveusb scripts to flake apps

- Move bootstrap.sh to scripts/ and add as flake app
- Move build-liveusb.sh to scripts/ and add as flake app
- Update usage comments to show nix run commands
- Improve build-liveusb.sh with better error handling (set -euo pipefail)
- Remove emojis from output messages for cleaner log output

Scripts can now be run consistently via:
  nix run .#bootstrap -- <hostname>
  nix run .#build-liveusb
