When form inputs lack `$bindState` bindings (like in the homepage contact form simulation), `useFieldValidation` was called with `bindings?.value ?? ""` as the path. All three inputs registered at the same `""` path but with different validation configs. Each `registerField` call overwrote the previous one, triggering a re-render where the other inputs would see a mismatched config and re-register -- creating an infinite loop.
- Fix infinite re-render loop caused by multiple unbound form inputs (Input, Textarea, Select) all registering field validation at path `""` with different `checks` configs, causing them to overwrite each other endlessly
- Stabilize context values in ActionProvider, ValidationProvider, and useUIStream by using refs for state/callbacks, preventing unnecessary re-render cascades on every state update
