Subject: [PATCH] Add Crowdsec integration to Traefik
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Configuration changes:
- Enable Traefik experimental plugins support
- Add Crowdsec bouncer plugin (maxlerebourg v1.3.3)
- Configure Crowdsec middleware in config.yml
- Connect Traefik to Crowdsec network
- Add IP whitelist middleware for internal network
- Update .gitignore to exclude crowdsec directory

Security enhancements:
- All routes now protected by Crowdsec threat intelligence
- Internal network IP whitelist for Traefik dashboard
- Crowdsec monitors all Traefik access logs
- Real-time blocking of malicious IPs

Protected services:
- Mealie (recipes.pkartchner.com)
- Gogs (git.pkartchner.com)
- Traefik Dashboard (internal network only)
