ESLint allowlists (only to shrink) for DatabaseSync, synchronous fs in src/main and direct window.goodbuddy subscriptions in components, plus a max-lines ratchet for App.tsx; docs demos and vendored scripts are no longer linted. perf:check (or GB_PERF_CHECK=1 perf:app) fails a non-throttled benchmark that exceeds build/perf-thresholds.json. Records the results in the PERF plan.
