chore: workspace eslint catalog, typescript dev dep, monorepo skill

- pnpm-workspace catalog: replace oxlint with eslint ^10.4.1.
- Add typescript dev dep (root) so vitest typecheck (stdlib) resolves tsc.
- Root vitest projects: configs/oxlint → configs/eslint.
- Update monorepo skill + add component-test-auditor agent.
