• icmptunnel 1.0.0-alpha -> 1.0.0
• logtop a0935ab -> 0.7
• ngrep 1.47.1 -> 1.49.0
• tor 0.4.8.0 -> 0.4.9.11
• avml 0.11.2 -> 0.20.0
• zenith 0.12.0 -> 0.15.0
• suricata 6.0.0-rc1 -> 8.0.6
• wireshark 2.6.17 -> 4.7.2

• frp 0.48.0 -> 0.71.0
• sslh 2.0 -> 2.3.1
• zmap 2.1.1 -> 4.4.0

Each binary was rebuilt from source in its Dockerfile
(build//Dockerfile), stripped and UPX-packed, then
smoke-tested on x64 and ARMv7 before landing here.

Reviewer checklist:

• spot-check one binary locally (./scripts/build.sh <tool> --extract)
• sizes look sane vs previous commit
