Summary

Add an AGENTS.md to new apps, so coding agents get the project commands and avoid the mistakes they commonly make in a Community CLI app. It stays tool-agnostic, per the discussion in #175.

• Commands to run, test, lint, typecheck and clean the build, and which changes need a native rebuild.
• Guardrails against reaching for Expo, deprecated APIs and the legacy native module APIs.
• Built-in Turbo Native Modules and Fabric Native Components as the default for native code.
• Library guidance: find libraries on React Native Directory, and never downgrade React Native or force past peer dependency conflicts to fit one.

Resolves #175

Changelog:
[General][Added] - Template: AGENTS.md with guidance for coding agents

Test Plan

• prettier --check template/AGENTS.md passes.
• Every link in the file resolves.
• npm run ios installing CocoaPods itself, and start --reset-cache, checked against the Community CLI source and docs.

@cortinico @cipolleschi Trying my best here to be both minimal + ecosystem agnostic with this first draft. This guidance becomes the default for everyone, so let's review thoroughly!

The updated commit aligns to what I was trying to convey. Thanks @huntie for this!
