Implement full link workflow between component slots on the wiresheet: - Link Mark / Link From / Link To context menu items for creating links - Link dialog with slot type validation and source/target swap button - Selectable link wires (click to highlight in red) with right-click delete - Undo/redo support for both add and delete link operations - Component deletion already cascades to remove related links Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

the names directly. A plain ``from app_state import is_dirty`` would copy the value,

so later rebinding would only ever be seen by the module that did it.
