validateLocalCloudflarePackages function

void validateLocalCloudflarePackages(Iterable<String> packages)

ローカル適用に必要な宣言・lock・実体を、依存を変更せず検証します。

packages accepts plain names or versioned specs such as @scope/name@^1.2.3. A versioned spec also requires the locked version to satisfy the range.

Implementation
