[AUTOMATIC] JS 1.51.2 => 1.52.0

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Dependency-only bump with no local code changes; risk depends on what
changed in purchases-js 1.52.0 upstream.
> 
> **Overview**
> Bumps the **`@revenuecat/purchases-js`** dependency in
`purchases-js-hybrid-mappings` from **1.51.2** to **1.52.0**, with the
matching **`yarn.lock`** entry updated. No changes to hybrid mapping
source or APIs in this repo—only the pinned JS SDK version.
