A small Go tool that wraps the `/etc/hosts` + `once deploy --disable-tls` recipe needed to host a Once app on a single-label `<name>.local`. Adds the hosts entry, runs the deploy, polls /up, and on removal cleans the hosts line that the Once UI orphans (including the orphan-only case, where the app is already gone). Bubble Tea TUI for interactive use; non-interactive CLI for scripts. Curated apps live in /etc/once-add/apps.toml; seeded with Writebook + Campfire on first run.
