Sometimes it's difficult to gauge the valid range of values for a
widget. Litegraph includes a "slider" widget which displays the distance
from the min and max values as a colored bar. However, this
implementation is rather strongly disliked because it prevents entering
an exact number. Vue mode makes it simple to add just the indicator onto
our existing widget.
In addition to requiring both min and max be set, not every widget would
want this functionality. It's not useful information for seed, but also
has potential to cause confusion on widgets like CFG, that allow
inputting numbers up to 100 even though values beyond ~15 are rarely
desirable.
As a proposed heuristic, the ratio of "step" to distance between min and
max is currently used, but this could fairly easily be changed to an
opt-in only system.

Adds support for entering math inside number widgets in vue mode

Migrates components to simple html elements (div and button) by
borrowing styling from the (reverted) reka-ui migration in #6985. The
existing (evil) litegraph eval code is extracted as a utility function
and reused.
This PR means we're entirely writing our own NumberField.
Also adds support for scrubbing widgets like in litegraph

### Known Issue
- Scrubbing causes text to be highlighted, ~~starting a scrub from
highlighted text will instead drag the text~~.
- It seems this can only be prevented with `pointerdown.prevent`, but
this requires a manual `input.focus()` which does not place the cursor
at location of mouse click.
(Obligatory: _It won't do you a bit of good to review math_)

## Summary
### Problem:
After [vue node compacting
PR](https://github.com/Comfy-Org/ComfyUI_frontend/pull/6687) the white
space within the node has been greatly reduced, lowering the min
intrinsic size, thus allowing us to reduce the amount we need to scale
up via ensureCorrectLayoutScale(), therefore increasing readability of
nodes. Great!
However, a side effect of reducing the scale factor means nodes with
larger min content will not be scaled up enough causing nodes to be too
large in many cases.
For example, if the min intrinsic width is very long due to input
length:
<img width="807" height="519" alt="image"
src="https://github.com/user-attachments/assets/a6ea3852-bed5-49b2-b10e-c2e65c6450b2"
/>
### Solution:
Allow for nodes to be resized less than their intrinsic min width. And
truncate widget inputs like many other node UIs do.
IMPORTANT: when a node is added via search or other, it will still get a
min size based on its intrinsic content it just wont be the min width!
So best of both worlds.
<img width="670" height="551" alt="image"
src="https://github.com/user-attachments/assets/f4f5ec8c-037e-472f-a5a1-d8a59a87c0b0"
/>
this means we choose a default min width and clamp resize to it. This
also means we have to remove the arbitrary min width values that were
sprinkled around the vue node widgets. They are not needed because
instead of min width, they can take up full width and inherit the sizing
from the node min width! This makes nodes like little browser windows
and widgets are just responsive elements with in. Much more natural imo.
### Bonus
- Set ensureCorrectLayouScale() to scale factor of 1.2 which means vue
nodes are now only being set 20% bigger than LG. That covers for the
height difference we cant change!
- Fix ensureCorrectLayouScale() to offset y position for groups / better
alignment
- Get rid of arbitrary inflexible min width like min-[417px] which
shouldnt have been used the first place
- Make Select and Input overlay portals width set to their content
## Changes
**What**:
- Node resizing behavior
- Node widget min width
- Widget input and slot truncation
- Misc arbitrary styling that should have been fluid

This pull request updates the design system color tokens and refactors
node and widget component styles throughout the codebase to use new,
more consistent CSS variables. The changes ensure that node and widget
components are styled using unified design tokens, improving
maintainability and theme support for both light and dark modes.
**Design System Token Updates**
* Added new component and node-related CSS variables for background,
border, foreground, and widget states in both light and dark themes in
`style.css`.

* Introduced `--color-graphite-400` and adjusted several existing color
assignments for better palette consistency.

* Updated semantic CSS variables to reference the new component/node
tokens for easier usage in components.
* Changed `--secondary-background-hover` to match
`--secondary-background` for improved hover consistency.
**Component Refactoring: Node and Widget Styles**
* Refactored Vue component classes and inline styles to use the new CSS
variables for node backgrounds, borders, and widget states, replacing
legacy variables like `bg-node-component-surface` and
`border-node-component-border` with `bg-component-node-background` and
`border-component-node-border`.

* Updated widget dropdowns, select, and input components to use
`text-component-node-foreground-secondary` for icons and foregrounds,
and new background variables for buttons and inputs.

## 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
```mermaid
graph TD
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.
