Unified read of Supabase members (admins/investors/collaborators) + everyone-members Blob (the /in and /zak signups). All sources, one table.
GET /invite?action=list-all-users (Supabase + role-claims) and GET /joinTeam?action=admin-list-everyone (everyone-members Blob).
Manifest at GET /coreManifest for Claude sessions.
Existing /admin remains the full management surface (conversations, engagement, invites, role changes).
/core is the unified read view; manage actions live on /admin until both are wired here.
