/**
 * Trigger Cooldown Tracker — PRI-363
 *
 * Manages cooldown state for trigger controller decisions.
 *
 * This is a plugin-layer concern because:
 * - Core (trigger-controller) is stateless and pure
 * - Cooldown state needs to persist across tool calls
 * - The map is scoped to the plugin's lifecycle
 *
 * EP-05: Loop State Freshness — each check reads fresh state from the map.
 * ERR-001: No `as` casts on map access.
 * ERR-002: Every rejected decision includes reason + nextAction.
