sanitize public mirror: drop personal IP and infra/customer hostnames

- trusted_ips.{list,map}: replace home IP with 127.0.0.1 + usage notes
- skill: resolve deploy host from gitignored target-host.local, ask if unset
  (no hardcoded server FQDN); customer host in WAF test -> <live-vhost>
- README / coraza README: registry FQDN in run examples -> placeholder
- 403 block page: drop hardcoded support link -> contact provider support
- CLAUDE.md: note whitelist files ship without real IPs
- .gitignore: ignore target-host.local and *.local
