[corridor-security]

Summary: This PR removes a dead external Discord link from documentation and does not modify executable code, authentication, authorization, data handling, or external integrations.

Risk: Low risk. No exploitable security vulnerabilities were identified because the change is limited to documentation link removal and does not introduce a new attack surface.
