[CHORE] lint-staged enforces --max-warnings=0 but CI/validate run plain eslint

[martian56]

Summary

lint-staged runs ESLint with --max-warnings=0 (fails on any warning), but the lint script used by CI and validate runs plain eslint . (exits 0 on warnings). The pre-commit gate is therefore stricter than CI, so warnings can accumulate on main.

Severity

Low (CI consistency)

Affected code

• lint-staged.config.mjs:8 — eslint --max-warnings=0 --fix ....
• ui/package.json:10 — "lint": "eslint ." (no --max-warnings), invoked by .github/workflows/ui-ci.yml:44 and package.json:13 (validate).

Suggested fix

Add --max-warnings=0 to the lint script in ui/package.json so the local hook, CI, and validate all enforce the same bar.
