`quak login` takes the server's API address from `--server` or `QUAK_SERVER`. `isServerAddress` refuses anything but an http or https URL with no query or fragment, there and in `Client.fromJSON`. The client's snapshot keeps a non-default `apiOrigin`, so the session file names the server and every later command uses it. Two servers can give two accounts, and two files, the same ID. A self-hosted account's default cache directory therefore names the server, and `metadata.json` records it: `Library.open` deletes a cache from another server whole. `originalOf` and `thumbnailOf` record the account in a cache that names none before storing a file, and `open` treats a cache with no collection as empty. This fixes #254 (closes #254). Model: opus-5-5
