Safe triage before extraction

Follow the firmware workflow before extraction. Binwalk-specific invariant: start with a signature/entropy scan; make -eM and --dd ".*" opt-in; use a fresh -C directory plus -d, -n, and -j; and enforce total output bytes with an external monitor/quota because Binwalk v2 has no total-output flag. -j limits each carved input region, but an external extractor may still decompress it into a larger tree.
