Add org-scoped data isolation across all server actions to prevent cross-org data leakage. Add read-only demo mode with mutation guards on all write endpoints. Multi-tenancy: - org filter on executeDashboardQueries (all query types) - org boundary checks on getChannel, joinChannel - searchMentionableUsers derives org from session - getConversationUsage scoped to user, not org-wide for admins - organizations table, members, org switcher component Demo mode: - /demo route sets strict sameSite cookie - isDemoUser guards on all mutation server actions - demo banner, CTA dialog, and gate components - seed script for demo org data Also: exclude scripts/ from tsconfig (fixes build), add multi-tenancy architecture documentation.
