chore: Upgrade React Native to 0.85.3 and React to 19.2.6

[mrousavy]

Summary

• Upgrade React Native to 0.85.3 across the workspace and bump tied RN CLI, Babel preset, Metro config, TypeScript config, and patched React Native package metadata.
• Fold in the React-family upgrade from chore: Upgrade React to 19.2.6 #3936: React 19.2.6, React DOM 19.2.6 for docs, and @types/react 19.2.15 across workspaces.
• Refresh the example app iOS Podfile.lock for RN 0.85.3 prebuilt React Native Core/Dependencies and Hermes 250829098.0.10.
• Keep the existing IPv6 dev-server React Native patch on react-native@0.85.3 because the upstream files still require the workaround.
• Keep app-level yargs@17.7.2 so RN codegen resolves the CommonJS-compatible yargs version instead of Nitro transitive ESM yargs@18 under Bun hoisting.

Validation

• bun install --frozen-lockfile
• bun run build
• bun --cwd apps/simple-camera tsc --noEmit
• bun --cwd docs tsc --noEmit
• bun --cwd docs build
• bun pm why react / react-dom / react-native / @types/react
• git diff --check

Notes

• This supersedes chore: Upgrade React to 19.2.6 #3936 so React, React DOM, @types/react, and React Native are validated as one combined install.
• Harness test failures can still be expected red; the build and lint/type/build validations above are the relevant checks for this dependency fold.
