RNC CLI incompatible with Xcode 27

[leotm]

Description

Raised and fixed earlier in

• Xcode 27 - /Applications/Xcode-beta.app/Contents/Developer/Applications/Simulator.app does not exist react/react-native#57160
• feat: Support DeviceHub for Xcode 27+ cli#2806 shoutout to @huntie

so needs a new @react-native-community/cli release (bump/tag/publish)

• v20.2.0 cli#2813

then couple bumps in this repo

• main (nightly)
• 0.86-stable (plus template bump to 0.86.1/2)

from

    "@react-native-community/cli": "20.1.0",
    "@react-native-community/cli-platform-android": "20.1.0",
    "@react-native-community/cli-platform-ios": "20.1.0",

to

    "@react-native-community/cli": "20.2.0",
    "@react-native-community/cli-platform-android": "20.2.0",
    "@react-native-community/cli-platform-ios": "20.2.0",

for early support i fixed @react-native-community/cli windows paths locally to build then patch @react-native-community-cli-platform-apple plus sourcemaps and type defs (patch since git specifiers and tarball URLs are incompat with yarn workspace monorepos)
