refactor(storage): rename dsh-domain to dsh-storage-domain

The bare 'domain' name was too generic for a published package. The
directory moves to packages/storage/storage-domain, the package becomes
@deepseek-ai/dsh-storage-domain, and the plugin/invariant names follow;
the ctx surface (ctx.storage.domain), the domain/changed event, and all
runtime behavior are unchanged. References, catalogs, graphs, and the
bilingual design note move together.
