Auto space for manual process-map edits

BA Copilot now has Auto space mode for manually editing process maps.

When you add a new BPMN element from the palette or context pad, BA Copilot can automatically make room for it instead of letting it land on top of existing shapes. Neighbouring elements to the right slide over, and the containing lane or pool grows if the new element needs more vertical room.

Auto space uses the same underlying spacing behaviour as the manual space tool, so connector waypoints and lane or pool resizing follow the editor's normal rules. Creating the element and making room for it are handled as one edit, so a single undo removes both.

The toggle is on by default and can be switched off from the process-map toolbar.
