ausboss 3d781bb0ec Float and Integer take the limits of what they are wired to

A Float wired to a sampler's denoise could be set above 1, where ComfyUI's
own Primitive node stops at 1. Both number boxes now follow their output to
every input it reaches, through Reroutes and into subgraphs, and keep to the
range all of those inputs allow: by typing, by the arrows and by a drag. A
value that is outside when the wire is made comes to the nearest limit, the
card shows the limits beside the value (0–1), and an unwired box takes any
number as before. No input was added, so saved workflows and API requests
are unchanged.

With it:
- A new box takes the value of the first input it is wired to, as the
  Primitive does. A box that came with a workflow or a paste, or one that
  was already set, keeps its own value.
- Float shows the decimals its steps reach (1.00 wired to denoise, 8.0
  wired to CFG) and goes past them only for a value that uses more. It read
  1.000 everywhere before.
- Integer's own limit goes from 2,147,483,647 to 9,007,199,254,740,991, the
  largest whole number a browser holds exactly, so a seed fits.

The walk over the graph is js/shared/wired_limits.mjs; the scrub control
gains setRange and a way to drop the zeroes its steps never reach. Help
pages, tests and the CHANGELOG entries are included.

Float

A number with decimals. Set one strength, scale, or CFG here, wire it to every node that needs it, and change it in one place.

Controls

Value (value): The number to send out. It starts at 0. The box shows the decimals its steps use (0.00) and holds up to three, so a typed 0.125 stays 0.125.

Limits

Wire the output to a setting that has limits and the box takes them over. Wired to a sampler's denoise, it goes from 0 to 1 and no further: type 1.5 and you get 1. The card shows 0–1 beside the value.

It works through a Reroute and into a box (subgraph) too.
Wired to two settings, it keeps to what both allow.
Unwire it and it takes any number again.
A new box takes the value of the first setting you wire it to, so wiring it up changes nothing until you move it. A box you have already set, or one that came with a workflow, keeps its own value.

Output

float: The value, unchanged.

For arithmetic on the way — scaling, clamping with min/max — feed this into Math Expression 🆎 instead of retyping derived numbers.

Technical details

The limits are those of the input the wire lands on, the way ComfyUI's own Primitive node takes them. When the inputs agree on a step, the fine step (Shift) is that step.
A value that is outside the limits when the wire is made is brought to the nearest one.
The box holds three decimals, or as many as the step it took over needs. It shows the decimals its arrow step reaches (at least one) and goes past them only for a value that uses more: 1.00 wired to denoise, 8.0 wired to CFG, 0.855 for a typed 0.855.
The limits are kept by the node's face. A value sent straight through the API is passed on as it is.
Wired only to inputs that share no value (one stops at 1, the other starts at 2), the box keeps no limits.
