Highlights

• Added the organization, owner, permission, and workspace foundations for personal and team workspaces.

• Added workspace-scoped automations, organization Studio assets, workspace public links, audit trails, retention/trash handling, and granular migration import/export policy.
• Added database provider abstraction, installer database provider selection, local Postgres compose setup, provider-aware backup/migration manifests, and Postgres-gated advanced knowledge settings.
• Improved Studio workspace destination/source pickers, mobile workspace navigation, email chat/attachments, markdown block dragging, markdown PDF sharing, and notebook preview behavior after workspace switches.
