This pull request refactors the node selection and pointer interaction
logic in the Vue node graph editor to improve multi-selection behavior,
clarify event handling, and enhance test coverage. The main change is to
defer multi-select toggle actions (such as ctrl+click for
selection/deselection) from pointer down to pointer up, preventing
premature selection state changes and making drag interactions more
robust. The drag initiation logic is also refined to only start dragging
after the pointer moves beyond a threshold, and new composable methods
are introduced for granular node selection control.
**Node selection and pointer event handling improvements:**
* Refactored multi-select (ctrl/cmd/shift+click) logic in
`useNodeEventHandlersIndividual`: selection toggling is now deferred to
pointer up, and pointer down only brings the node to front without
changing selection state. The previous `hasMultipleNodesSelected`
function and related logic were removed for clarity.

* Added new composable methods `deselectNode` and
`toggleNodeSelectionAfterPointerUp` to `useNodeEventHandlersIndividual`
for more granular control over node selection, and exposed them in the
returned API.

**Pointer interaction and drag behavior changes:**
* Updated `useNodePointerInteractions` to track pointer down/up state
and only start dragging after the pointer moves beyond a pixel
threshold. Multi-select toggling is now handled on pointer up, not
pointer down, and selection state is read from the actual node manager
for accuracy.

**Test suite enhancements:**
* Improved and expanded tests for pointer interactions and selection
logic, including new cases for ctrl+click selection toggling on pointer
up, drag threshold behavior, and mocking of new composable methods.

* Updated test setup and assertions for node event handlers, ensuring
selection changes are only triggered at the correct event phase and that
drag and multi-select logic is covered.

These changes make node selection more predictable and user-friendly,
and ensure drag and multi-select actions behave consistently in both the
UI and the test suite.

This pull request refactors the node selection logic in the Vue nodes
event handler composable to simplify the function signature and improve
single vs. multi-selection behavior. The main change is the removal of
the `wasDragging` parameter from the `handleNodeSelect` function, with
selection logic now determined by the current selection state. Related
test code is updated to match the new function signature.
**Node selection logic improvements:**
* Refactored the `handleNodeSelect` function in
`useNodeEventHandlersIndividual` to remove the `wasDragging` parameter,
making the function signature simpler and relying on selection state to
handle single vs. multi-selection.
* Updated the selection logic to check if multiple nodes are already
selected using `isLGraphNode`, and only perform single selection if not.
**Code and test updates:**
* Updated all calls to `handleNodeSelect` in the composable to remove
the `wasDragging` argument, ensuring consistent usage throughout the
codebase.

* Updated all related test cases to use the new `handleNodeSelect`
signature without the third parameter.

**Utility import:**
* Added an import for `isLGraphNode` from `@/utils/litegraphUtil` to
support the updated selection logic.## Summary
