AWS cli documentation change
Summary
Renamed and completely restructured command from 'devops-agent initiate-chat-for-case' to 'securityagent initiate-provider-registration'. Changed from a chat initiation command to a provider registration command with OAuth security features.
Security assessment
This change introduces documentation for a new security agent command that handles OAuth provider registration with CSRF protection. The output now includes a 'csrfState' token for OAuth security, which is a security feature. However, there's no evidence this addresses a specific security vulnerability or incident - it appears to be documentation for a new feature.
