v1.6.0 — React 19, Vite 8, TypeScript 6, ESLint 10

Highlights

Major frontend framework upgrade — React 18 → 19, Vite 7 → 8, TypeScript 5 → 6, ESLint 8 → 10 — plus post-upgrade cleanup to remove dead dependencies and wire up previously orphaned lint rules.

Added

• React 19 with idiomatic createRoot / StrictMode named imports
• Vite 8 build toolchain
• TypeScript 6 with src/vite-env.d.ts for CSS side-effect imports
• ESLint 10 with flat config
• @typescript-eslint v8 (fixes 6 high CVEs from minimatch ReDoS in v6)
• eslint-plugin-react-hooks v7 — enforcing rules-of-hooks (error) and exhaustive-deps (warn)
• eslint-plugin-react-refresh v0.5 — enforcing only-export-components (warn)
• @testing-library/react v16 and jsdom v29
• Re-enabled tsc --noEmit and npm audit checks in CI

Changed

• React 18 → 19, react-dom 18 → 19
• Vite 7 → 8, @vitejs/plugin-react 4 → 6
• TypeScript 5 → 6
• ESLint 8 → 10, @eslint/js 9 → 10
• @testing-library/react 14 → 16, jsdom 23 → 29
• main.tsx modernized to use named imports
• import.meta.env no longer needs as any cast

Removed

• react-router-dom — was never imported in source; phantom dependency removed
• autoprefixer — redundant with Tailwind CSS v4
• eslint-plugin-react — incompatible with ESLint 10 and unused
• Duplicate root-level vite-env.d.ts — consolidated into src/

Fixed

• ESLint plugins installed but not configured — now enforced
• CI was skipping tsc --noEmit and npm audit — both re-enabled (pass clean)
• 6 high-severity CVEs resolved via @typescript-eslint v6 → v8
