feat: warm-up deps — ts-reset, web-vitals, RHF devtool, query-broadcast
Four low-risk adds before the Zod 4 / drizzle-zod headliner:
- @total-typescript/ts-reset: tightens TS stdlib types globally (JSON.parse
→ unknown, fetch().json() → unknown, .filter(Boolean) narrows, Set
literals respect typed Set targets). Caught 179 latent type errors;
fixed all production sites (8 files) and added `any` cast escape hatch
in test files (ESLint exemption scoped to tests/).
- web-vitals + /api/v1/internal/vitals endpoint + WebVitalsReporter
client component: establishes Core Web Vitals baseline (LCP/INP/CLS/
FCP/TTFB) via navigator.sendBeacon. Required before optimisation work.
- @hookform/devtools + FormDevtool wrapper: dev-only RHF state inspector,
lazy-loaded via next/dynamic so the chunk is excluded from prod
bundles entirely.
- @tanstack/query-broadcast-client-experimental: cross-tab cache sync
via BroadcastChannel — wired in query-provider.tsx, 1-liner.
Audit doc updated with sections 35 + 36 (PDF stack overhaul + comprehensive
second-pass package sweep) covering ~20 package adoption candidates and
4-5 deprecation candidates.
Verified: tsc clean, vitest 1293/1293 pass.
