ci: replace hardening workflow with RTL lint

Browse Source 
The template CI tried to re-harden from scratch in GitHub Actions, but
cf harden requires a TTY for Docker and the design takes 8+ hours.
Replace with a Verilator lint check. Hardening and precheck are run
locally on snoke; GDS/SPEF are uploaded via cf push.
