    libide/foundry: simplify base implementation to check for program
    
    This, so far, should almost never get used, so just provide a reasonable
    fallback for new implementations. Runtime should override this to use their
    run contexts as appropriate (or something faster when possible).
    
    The GbpHostRuntime already handles the special case above so we can just
    go ahead and delete that case.
