GUI launch (docker/podman) now pre-flights the noVNC port (6080): if it's
already bound, a modal names the holding pid and asks before killing it and
proceeding — never a blind `bind: address already in use` collision.
Sudo capture is now uniform across every backend installer. Previously only
Docker fed the masked-modal password through `--stdin-pass`/`sudo -S`; the
captured password was silently dropped for Podman/Multipass and never wired
for VirtualBox, and those scripts used bare `sudo` (which hangs/corrupts a
raw-mode tty). Now:
- shared `run_ensure()` feeds the password to any ensure-*.sh via stdin
- podman/multipass/vbox scripts gain the docker sudo ladder
(interactive `sudo` / `--yes` `sudo -n` / `--stdin-pass` `sudo -S -p ''`)
- podman's apt path wrapped in `sh -c` so one sudo covers update+install
- vbox GUI path preflights `sudo_ready()` with actionable guidance, falling
back to fail-fast `sudo -n` instead of a tty hang

Previously, launching a sandbox on a machine without the backend binary
died with a raw "not installed" error and no path forward. Now the
missing backend can be installed in-line, gated on explicit consent, so
a fresh checkout can go from zero to a running sandbox without leaving
the TUI.
Folded into the existing `/sbx launch` verb rather than a new command
(menu is already dense): `/sbx launch docker|multipass [image] install`.
The `install` token opts in; without it the user gets an actionable
error naming the exact retry. The token is filtered out of positional
image parsing so it never shadows a custom image.
The install runs off-thread inside the existing spawn_launch task,
before provisioning, so the TUI never blocks and the *launching guard is
cleared via BrokerMsg on failure. A fresh Docker install also leaves its
daemon up, so launch proceeds straight through.
Scripts (detect-first, never silent, --plan dry-run, idempotent if
already present):
- ensure-multipass.sh (new): Linux→snap (clear failure if snapd absent),
macOS→brew cask, Windows→winget.
- ensure-docker.sh: new --install mode using Docker's OFFICIAL,
GPG-verified apt repo (docker-ce) on Debian/Ubuntu, with dnf
(Fedora/RHEL) and pacman (Arch) fallbacks. Deliberately avoids piping
get.docker.com into a root shell. Existing daemon-start path intact.
sbx.rs: docker_installed()/multipass_installed() detectors and
ensure_docker_install()/ensure_multipass_install() wrappers; ENSURE_MULTIPASS const.
ui.rs: help text documents the [install] option on both backends.
