Summary

Rewrites docs/share_wifi.md to properly document scripts/share_wifi.sh and scripts/stop_share_wifi.sh, and links it from the README's More documentation section.

Problem

The share-wifi doc existed as an unlinked stub: it wasn't reachable from the README, and it told users to hand-edit interface names and subnet even though the script auto-detects both. It also didn't explain what the scripts actually do or their side effects.

Solution

Rewrite the doc to match the current scripts: how detection works, what the host side sets up (IP forwarding + NAT), what the Jetson already provides out of the box (address, DHCP, default route via 192.168.55.100 — verified in L4T's nv-l4t-usb-device-mode-config.sh), the missing-DNS gotcha with a one-line fix, and caveats (iptables flushing clobbers existing firewall rules, nothing persists across reboot). Add the doc to the README's More documentation list.
