List files

List the files visible to the caller in the current space. Requires the files:read permission (the family gate — mirrors runs:read); on top of it, each row is filtered by its own container ACL, so a member sees the files of the runs it may read (the whole space with runs:read-all, otherwise the runs it launched) plus its own chat and container-less files, and end-users see only their own. Filter by purpose, runId, packageId, chat_session_id, or a chat session's complete context; paginate with startingAfter + limit. An unknown query parameter or an invalid purpose is rejected with 400.
