feat: add 7zz for CHM documentation extraction

Download static 7-Zip binary at Docker build time for extracting Microsoft Compiled HTML Help (.chm) files. Follows the same pattern as the existing Himalaya CLI installation. 7zz is scraped from 7-zip.org/download.html at build time.
Merge pull request 'fix: use ln -sf instead of update-alternatives --set for iptables-nft' (#28 ) from fix/vpn-iptables-nft-v3 into master

Hermes	8dff094768	fix: use ln -sf instead of update-alternatives --set update-alternatives --set fails because the base image only registers iptables-legacy as an alternative. The iptables-nft binary (/usr/sbin/iptables-nft) exists but isn't in the alternatives database. Direct ln -sf bypasses this.	2026-05-13 12:58:43 -04:00
