10/// reachable.
11///
12/// `Ok(true)` — `docker buildx version` ran and exited zero.
13/// `Ok(false)` — `docker` ran but the `buildx` subcommand exited non-zero
14///   (typically: docker is present but buildx plugin not installed).
15/// `Err(_)` — `docker` itself could not be spawned (binary missing,
16///   permission denied). Distinct from `Ok(false)` so callers can log the
17///   underlying `io::Error` at trace level when surfacing "docker not
18///   available" vs. "docker installed but buildx missing".
