> [!NOTE]
> **Low Risk**
> Low risk metadata-only change that renames the React SDK identifier;
main risk is breaking any tooling that still expects the old `react`
key.
> 
> **Overview**
> Updates `.sdk_metadata.json` to rename the React Web SDK entry key
from `react` to `react-client-sdk`, aligning the SDK metadata identifier
with its wrapper name/release tagging.
