When developers run example-mini or example-nested-mini through their ios/pods scripts on Xcode 26.4+, those apps still use the same React Native 0.80 fmt 11.0.2 pod but their Podfiles keep the default C++20 setting. This workaround only patches the host app, so the same fmt build failure remains for the other Metro iOS examples outside the default host E2E path.

Description
Restores the Metro-specific TypeScript 7 updates intentionally split from #4878.
node10resolution;ts-jestwith@swc/jestformetro-plugin-rnc-cli;fmt11.0.2 pod as C++17 for Xcode 26.4+ compatibility.Publishable Metro packages continue compiling with TypeScript 6; TypeScript 7 runs at the consumer/example boundary. The originally reported iOS failure occurred in CocoaPods project generation, outside TypeScript compilation. A fresh PR build passed CocoaPods and then exposed the known
fmtC++20 failure under Xcode 26.5, so the workaround targets only thefmtpod and leaves every other pod on C++20.Validation:
pnpm install --frozen-lockfilepnpm run ci:local --only=build-metrogit diff --checkThe Metro build, publint, tests, lint, and Android and iOS E2E passed. Local mobile E2E was unavailable because Maestro and the required Ruby 3.4.9 are not installed. The repo-wide Prettier check also reports an unrelated existing generated file:
packages/playground/src/generated/bridgeRuntimeFiles.ts.No changeset: this PR changes examples, development dependencies, and test/build configuration without changing published package behavior.
