Dsh Annotation Plugin

Key features

• Host half (dsh.bundle + cordis.patch.yml): an annotation plugin that records quotes as log-only session events (annotation/added / annotation/removed), exposes a Typert Remote (record / list / discard), and materializes pending quotes into the model-facing message batch at agent/pre-step.
• The Host half uses the namespace plugin form (name / inject / apply named exports).
• Browser half (dsh.client)a quote button on each assistant message and a floating, collapsible pending-quote card above the composer.
• Do not add an export default — the Loader's unwrapExports would discard the namespace.
• The browser half mounts its own Typert Remote contribution (ctx.remote.$mount) because the published @deepseek-ai/dsh-api-remotes does not carry the annotation namespace.
