// electron-builder >=26 injects an "!**/node_modules/**" ignore into every
// extraResources/extraFiles pattern list (app-builder-lib/out/fileMatcher.js),
// and that ignore cannot be overridden by any later positive filter pattern —
// verified empirically with a minimal fixture on 26.15.3. The standalone
// server resolves better-sqlite3 (and other runtime deps) from the *primary*
// node_modules at resources/app/node_modules (see
// prepare-electron-standalone.mjs: "Verify better-sqlite3 Node-API prebuilds in
// the primary node_modules"), so without this hook the packaged desktop app silently loses its native
// SQLite driver and falls back to sql.js — the exact regression guarded by
// issue #7592's cold-restart smoke check.
