[BUG] useFlag hooks display stale EvaluationDetails when flag value unchanged but metadata differs

[beeme1mr]

Observed behavior

When a flag is re-evaluated and the value remains the same but other EvaluationDetails fields change (e.g., reason, errorCode, variant, flagMetadata), components using useFlag or related hooks continue to display the old EvaluationDetails instead of the updated metadata.

Expected Behavior

Components should re-render and display updated EvaluationDetails whenever any field changes, not just the value.

Steps to reproduce

1. Set up a React component using useBooleanFlagDetails (or similar hook)
2. Mount the component while the provider is NOT_READY (flag evaluates with reason: "ERROR", errorCode: "PROVIDER_NOT_READY")
3. Wait for the provider to become READY (same flag value but now reason: "STATIC", no error code)
4. Observe that the component's EvaluationDetails still shows reason: "ERROR" instead of reason: "STATIC"
