Subject: [PATCH] chore(security): force @xmldom/xmldom and postcss via npm
 overrides
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds package.json overrides to force patched versions of two vulnerable
transitive build-tool dependencies:

- @xmldom/xmldom >=0.8.13: fixes 5 HIGH CVEs (XML injection CVSS 7.5,
  DoS, node injection via CDATA/comments/processing instructions). All
  within the same major version — no API break.
- postcss >=8.5.10: fixes GHSA-qx2v-qp2m-jg93 (XSS via unescaped
  </style>, CVSS 6.1). Same major v8.x — no API break.

Both packages appear only in Expo/Metro build tooling, not the app
bundle shipped to users. Reduces npm audit from 6 HIGH + 22 MODERATE
to 0 HIGH + 28 MODERATE. Remaining MODERATE items require Expo SDK 56
or have no upstream fix available.

uuid (<11.1.1) override was evaluated and deferred — forcing v9→v11
risks breaking the native iOS xcode npm package used by
@expo/config-plugins.
