Move panes between Workspaces by drag, context and dor - #887

Consolidate the move coordinator's consent, endpoint and close paths, rechecking both Walls after every await; flush both Walls together and publish the response once. Hold Window writes with a flag rather than a frozen snapshot, and fence Workspace saves through `serialize`. Measure drag targets once per gesture through the shared tab-element helpers and touch the highlight only when the target changes. Share the closed-select key handling with the browser-actions picker, parse the dor destination in one helper, and replace repeated spec rules with pointers to layout.md. Add a regression test for an iframe that appears during the persistence flush: dor refuses and the GUI prompts. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Panes and minimized Surfaces can now move to another Workspace by dragging to its tab, or to
+for a new Workspace. Terminal and Tool contexts also offer a Workspace picker; browsers use dragging.dor move <surface> <workspace>anddor move <surface> --newexpose the same operation.Moves preserve terminal Sessions and reconnect agent-browser Surfaces. Plain iframes reopen at their saved URL after a Window-wide typed confirmation; dirty or pending Tools refuse the move. Membership, refs, activity projections, and persistence move together, with rollback before commit and protection against stale saves. Moved terminals explain the new ref scope and stable-ID usage. A sole Surface cannot create an equivalent new Workspace.
The title explanation is separately changed to a bug icon directly beside the title, including VS Code.
Validation:
pnpm testandpnpm build.builtin:fileeditor refreshes when clean and refuses a move with unsaved edits./simplify; reviewed and tested the resulting changes.
