* Add high res wheel event handling
Attempts to resolve high res wheel event handling. First pass.
* [Test] Add comprehensive TDD tests for device detection spec
* Implement efficient timestamp-based device detection for mouse/trackpad
- Add timestamp-based detection without creating timers on every event
- Implement 500ms cooldown period to prevent rapid mode switching
- Support Linux wheel event buffering with divisibility detection
- Maintain backward compatibility with isTrackpadGesture()
- All 69 device detection tests passing
* Remove magic number and unused code from device detection
- Replace hardcoded 500ms with CanvasPointer.trackpadMaxGap constant
- Update trackpadMaxGap from 200ms to 500ms for cooldown period
- Remove unused lastIntegerDelta property that was only set but never read
- Update tests to remove references to removed property
* Update old CanvasPointer tests to match new device detection behavior
- Update tests to require two-finger panning (deltaX && deltaY) for trackpad detection
- Fix expectations to match new default mouse mode behavior
- Small values alone no longer automatically mean trackpad
- All 15 legacy tests now pass with new implementation
* Consolidate CanvasPointer tests and remove redundant test file
- Add backward compatibility test to comprehensive test file
- Remove old CanvasPointer.test.ts that was created on this branch
- Old file had 15 tests, mostly redundant or testing unused features
- New comprehensive file now has 70 tests with full coverage
- Preserves the only unique test (lastTrackpadEvent backward compatibility)
* Simplify conditional assignment with ternary operator
* Remove redundant code
* Simplify comments to remove redundant explanations for developers
* Refactor device detection for improved readability and maintainability
* Inline immediately-returned variable for conciseness
* Cleanup: Remove redundant code, fix style
* Update test expectations
* Guard against invalid state in event comparison
* Fix node.js setTimeout type issue
Caused by node.js types being loaded globally.
* Remove any type from unit test
* Address PR feedback
- Add static value to handle the high-res maximum buffer time.
- nits
- Modified removeInput/removeOutput to skip disconnect operations when node has no graph
- Both methods now safely handle nodes that aren't part of a graph
- Added comprehensive tests for the new behavior
- Fixes#5037
* [bugfix] Fix widget disconnection issue in subgraphs
When disconnecting a node from a SubgraphInput, the target input's link
reference was not being cleared in LLink.disconnect(). This caused
widgets to remain greyed out because they still thought they were
connected (slot.link was not null).
The fix ensures that when a link is disconnected, the target node's
input slot is properly cleaned up by setting input.link = null.

* [test] Add tests for LLink disconnect fix for widget issue
Add comprehensive tests for the LLink.disconnect() method to verify
that target input link references are properly cleared when disconnecting.
This prevents widgets from remaining greyed out after disconnection.
Tests cover:
- Basic disconnect functionality with link reference cleanup
- Edge cases with invalid target nodes
- Preventing interference between different connections

## Summary
This PR fixes#4681 by building upon the foundation laid in PR #1182
(litegraph.js). It prevents incompatible type connections when dragging
from a normal node's output to a SubgraphInputNode's occupied slot.
Before:
https://github.com/user-attachments/assets/03def938-dccc-4b2c-b65b-745abf02a13b
After:
https://github.com/user-attachments/assets/7a0a2ed4-9ecd-4147-be56-d643d448d4cb
## Background
PR #1182 implemented:
- `isValidTarget()` method in SubgraphInput/SubgraphOutput classes for
validation
- Visual feedback during drag (40% opacity for invalid targets)
- Validation at the slot level
However, there was a missing piece: while the visual feedback correctly
showed invalid targets, the actual connection would still be made when
dropped.
## Changes
This PR extends PR #1182 by adding the missing connection prevention:
1. **Added `canConnectToSubgraphInput()` method** to render link
classes:
- `MovingOutputLink`
- `ToOutputRenderLink`
- `FloatingRenderLink`
- All methods use the existing `SubgraphInput.isValidTarget()` from PR
#1182
2. **Added validation in `LinkConnector.dropOnIoNode()`**:
- Checks `canConnectToSubgraphInput()` before allowing the connection
- Logs a warning when rejecting invalid connections
- Follows the same pattern as regular node connections
3. **Added `isSubgraphInputValidDrop()` method**:
- Provides validation for hover states
- Ensures consistent validation across the UI
