Greptile Summary

This PR adds validation to prevent stateful components or hooks from being used in the document root (specifically head components). The change stores the HTML component before returning it and checks if it contains any hooks using _get_all_hooks(), raising a ValueError if hooks are detected.

Key changes:

• Stores HTML component in variable before returning (instead of direct return)
• Calls _get_all_hooks() to detect any React hooks in the component tree
• Raises descriptive error if hooks are found in head components

Potential issue identified:

• The _get_all_hooks() method may not comprehensively detect all hooks because it only traverses self.children, not self._get_components_in_props(), unlike similar methods such as _get_all_refs() and _get_all_custom_code()

Confidence Score: 3/5

• This PR is likely safe to merge but requires verification of hook detection coverage
• The change adds important validation to prevent stateful components in document root, which is good for catching configuration errors. However, there's a potential gap in the implementation where _get_all_hooks() may not detect hooks in components passed as props (only checks children, not components in props). This could lead to false negatives where invalid components slip through. The logic should be verified to ensure comprehensive hook detection before merging.
• Verify that _get_all_hooks() in reflex/components/component.py:1798 properly detects all hooks, including those in components passed as props
