Pull request overview

This PR adds a new runtime wrapper to persist a workspace across conversational exchanges by hydrating from the last assistant message’s file content-parts and (on success) emitting workspace files back as content-part attachments.

Changes:

• Introduces ConversationalWorkspaceRuntime to hydrate from conversation history and dehydrate workspace files as file content-parts before the final assistant endMessage.
• Adds CAS URI helpers (build_cas_uri, parse_attachment_id) and WorkspaceHydrator.hydrate_files to support registry-less hydration from history.
• Adds comprehensive tests for hydration/dehydration behavior and bumps package version to 0.12.2.
