Add rules covering bug prevention (noLeakedRender, noFloatingPromises, noImportCycles, noReactForwardRef), security (noScriptUrl, noAlert), performance (noAwaitInLoops, useTopLevelRegex), and code style (noNestedTernary, useGlobalThis, useNullishCoalescing, useSortedClasses, plus ~40 more). Fix all violations: extract top-level regex constants, guard React && renders with boolean coercion, refactor nested ternaries, replace window with globalThis, sort Tailwind classes, and introduce expectDomainError test helper to eliminate conditional expects.
