feat(iac): establish Ansible baseline for Nginx, SearXNG, Valkey, and Certbot

- Reverse-engineer live Debian 13 (trixie) VPS state at miguelpedro.xyz.br
- Add modular Ansible roles: common, certbot, valkey, searxng, and nginx
- Encrypt SearXNG secret_key using ansible-vault in group_vars/all/vault.yml
- Cleanly remove unused example.com Nginx stub symlink (sites-enabled/miguelpedro.xyz.br)
- Scaffold cgit + fcgiwrap role (cgit_enabled: false) for upcoming deployment
- Add DISCOVERY_REPORT.md, COMMAND_LOG.md, README.md, and AGENT_INSTRUCTIONS.md with Self-Updating Protocol
