/**
 * search Tool
 *
 * Semantic search of institutional memory without action context.
 * Unlike recall (which is "I'm about to do X, warn me"), search is
 * pure exploration ("show me what we know about X").
 *
 * No side effects: no variant assignment, no session state mutation,
 * no surfaced scar tracking.
 *
 * Performance target: 500ms
