fix(io): prevent silent failure when writing restart file
Previously, if
global_out_dirdid not exist or lacked write permissions,std::ofstreamwould silently fail. The MD simulation would continue running without saving restart points, leading to potential loss of computational progress.This commit adds an
is_open()check inMD_base::write_restart. It now prints a clear error message tostd::cerr.
