Replace workspace system with pinned flows API (pin/unpin/list/reorder). Rename user-facing labels: Tree→Flow, Procedure→Project. Add sidebar nav sub-items for flow type filtering. Remove 11 workspace files, add migrations 037-038, clean all workspace references. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
