Upgrade dev dependencies to latest

Bump all devDependencies to current latest, including majors: eslint 10,
TypeScript 6, jsdom 29, @types/node 25, yargs 18. A clean resolve moves
vite to 8.x (via vitest), past the <=7.3.1 ReDoS range, so pnpm audit
reports no known vulnerabilities. No runtime dependencies and the
published src/ is unchanged, so package consumers are unaffected.
