// planner never schedules `actool` for it (verified: even a full re-plan skips
// it). So instead we add a shell-script phase that runs `actool` directly and
// drops the compiled Assets.car into the extension bundle. Marked
// alwaysOutOfDate so the build system always runs it.
//
// Idempotent across re-runs. Returns true when it added the phase, false when
// it was already present. Throws when the target does not exist — that means
// this ran before expo-widgets created the target (plugin ordering bug) and
// silently skipping would ship a widget without its assets.
