Move without moving data

Made a typo in an array name? Created data in the wrong group? Fixing it on traditional cloud storage means downloading every chunk, writing it back under the new key, and deleting the original — gigabytes of transfer for a one-character rename. With Icechunk's move, it's instant: just a small metadata update.
