This commit introduces a new `rootfs` package that provides an encrypted passthrough storage system. The `LocalStorage` implementation uses the local file system as its backing store and encrypts all data at rest using the `chachapoly` package. The functionality is exposed through the main `crypt` package, providing a clean and simple API for creating and interacting with encrypted file-based storage.
