v1.4.0

Added

• Quick-add menu on empty-canvas connection drop — drag a connection from a node's handle and release it on empty canvas to get a searchable node picker at the drop point instead of losing the connection. Picking a type creates that node there and auto-wires the dragged connection to it. Direction-aware: dragging from a source handle excludes Trigger (it has no target handle to satisfy the drag); dragging from a target handle offers Trigger but not compound blocks (no single well-defined exit point to wire).

Fixed

• Compound-block entry point was assumed to be the first node, which was wrong for repeat_while — its first node is the loop body, not the while-condition that actually runs first (found while wiring quick-add's auto-connect for compound blocks). parallel also has two independent branches with no single entry at all. block-factories.ts now returns an explicit entryNodeIds per block instead of callers guessing nodes[0].
