fix: TypeScript error when trying to access HTMLRules[key]

[coliff]

The original code had a TypeScript error when trying to access HTMLRules[key] using dynamic key access: )

Solution
I replaced the problematic code with a cleaner, more type-safe approach using Object.values(): )

Why this works better:

• Type Safety: Object.values() properly preserves the type information, so TypeScript knows that each rule is of type Rule
• Cleaner Code: No need for type assertions or @ts-expect-error comments
• More Direct: We directly iterate over the rule objects instead of getting keys and then accessing values
• ESLint Compliant: No linting errors about using any type

Verification:
✅ TypeScript compilation passes (npm run build succeeded)
✅ All tests pass (324 tests passed)
✅ Linting passes (no warnings or errors)
✅ Code formatting is correct

The issue has been completely resolved with a clean, type-safe solution that maintains all existing functionality while eliminating the TypeScript error.
