## Summary
Fixes https://github.com/Comfy-Org/ComfyUI_frontend/issues/5692 by
making widget link connection status trigger on change so Vue widgets
with connected links could properly switch to the `disabled` state when
they are implicitly converted to inputs.
## Changes
- **What**: Added `node:slot-links:changed` event tracking and reactive
slot data synchronization for Vue widgets

A[Widget Link Change] --> B[NodeInputSlot.link setter]
B --> C{Is Widget Input?}
C -->|Yes| D[Trigger slot-links:changed]
C -->|No| E[End]
D --> F[Graph Event Handler]
F --> G[syncNodeSlotData]
G --> H[Update Vue Reactive Data]
H --> I[Widget Re-render]
style A fill:#f9f9f9,stroke:#333,color:#000
style I fill:#f9f9f9,stroke:#333,color:#000
```
## Review Focus
Widget reactivity performance with frequent link changes and event
handler memory management in graph operations.

## Summary
Fixed increment/decrement button lockup in number widgets when values
exceed JavaScript's safe integer limit (2^53 - 1).
## Changes
- **What**: Added precision-aware button disabling and user feedback to
`WidgetInputNumberInput` component using
[Number.isSafeInteger()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/isSafeInteger)
- We still need to support values greater than 2^53 because they may be
in workflows.
## Review Focus
JavaScript floating-point precision behavior at scale - buttons hide
when arithmetic operations like `value + 1` would be unreliable due to
IEEE 754 limitations. Test coverage includes edge cases (NaN, Infinity)
and boundary conditions at MAX_SAFE_INTEGER.
