Address review feedback from freben

- Use cli-defaults instead of listing individual CLI modules in
  create-app template and root package.json
- Move nodeTransform config files from cli-module-build to cli-node
  to avoid cross-module direct imports
- Rename cli-module-create-github-app to cli-module-github
- Start createCliModule init chain with Promise.resolve()
- Deduplicate exitWithError in runCliModule.ts
- Extract shared isCommandNodeHidden to @internal/cli
- Add explanatory comment for fromArray deduplication field
- Restore error for cli role packages missing bin in runCliExtraction
