 * never touched (the seeded flag is set without creating anything).
 * Definitions are complete: role, ability allowlist, chat + send-to +
 * drag triggers, and full system prompts, so a fresh site can talk to
 * an agent the moment the feature flag turns on and a connector is
 * configured. Abilities that aren't registered on the site (the ai/*
 * family ships with the AI experiments plugin) are skipped by the
 * runner at tool-build time — allowlisting them here costs nothing
 * and lights them up when the provider plugin lands.
