Context

rtk discover --all shows iptables as an unhandled command:

• 103 invocations in the last 30 days
• Typical usage: listing firewall rules, checking INPUT/OUTPUT chains

Request

Add an RTK rewrite/filter for iptables output. Rule listings can be very verbose, especially with Docker's auto-generated chains.

Example commands

sudo iptables -L INPUT -n --line-numbers
sudo iptables -L -n -v
sudo iptables -S
