/**
 * Create the reference_search tool.
 *
 * Index design: the reference index (`allRefs`) is captured ONCE at tool
 * creation time from the live roles array. There is deliberately NO
 * module-level cache (unlike asset-search.ts's `_cachedAssets`), so hot-reload
 * needs no `invalidateReferenceIndex()` hook: the full-reload path rebuilds
 * this tool instance via the dispatch-service restart cascade (tool-service
 * re-init re-assembles buildCanonicalTools with the in-place-mutated
 * resolvedRoles). Reference file CONTENTS are read fresh from disk on every
 * execute() — only the metadata snapshot (which references exist) lives in the
 * closure, and that is refreshed whenever the tool is re-created.
