warn_if_previous_crash

At startup, scan the crash directory and report the latest crash without destroying the forensic file. A crash from the running daemon version stays prominent; an older-version crash is retained as a quiet archive notice. Best-effort and silent on directory errors.

write_crash_log_file

v1.4.97 P1-D-D: synchronously write a crash log file.
