/**
 * Canonical vocabulary of per-agent presentation icons.
 *
 * These are stable string names (kebab-case) persisted in `agent_settings.icon`
 * and validated on write. They are deliberately NOT lucide component references
 * here so this module stays server-safe (importable by the validator, the API
 * route, and `setup.ts` seeding) — the string → lucide component mapping lives
 * in the client-only `components/agentChips.tsx` (`AGENT_ICON`).
 *
 * Keep this list and the client `AGENT_ICON` map in sync: every name here MUST
 * have a component entry, and the `agentChips.test` guard enforces it.
