feat: frontend tests — import/export validator + unit tests + CI integration

- tests/frontend/validate-imports.mjs: 0 errors on 13 modules, 79 exports Detects: missing exports, broken imports, const reassignments - tests/frontend/unit.test.mjs: escapeHtml, state object, module syntax - Added to CI lint job (runs after Ruff + Mypy)
