Writes to a read-only artifact now come back with a clear reason

Refused writes to the artifact database can now report that the document is read-only, and that nothing in a refused batch was written

What

Writes to the artifact database can now fail with a store_read_only error. The message says the document is read-only, including documents that are page-only. When the write was part of a batch, the message says the batch is all-or-nothing and nothing was written.

Why

Claude gets a clear reason when an artifact write is refused, rather than a vague failure. This only happens when the server returns that error.
