Adds a user to the Submariner team's Konflux RBAC, granting them access to the Web UI and namespace.

Usage:

/add-team-member alice maintainer
/add-team-member bob admin
/add-team-member charlie  # Defaults to contributor (read-only)

Permission Levels:

• admin: Full CRUD on all resources, manage secrets/serviceaccounts
• maintainer: Create/update components, releases, snapshots (most users need this)
• contributor: Read-only access to Web UI and resources

What it does:

• Validates username format
• Checks if user already exists in role
• Adds user to appropriate RBAC file (alphabetically)
• Rebuilds auto-generated manifests
• Creates signed commit
• Shows review instructions
