Function renderProgressBar

renderProgressBar(options: RenderProgressBarOptions): string
Renders a deterministic, single-line progress bar.

This function is framework-independent and does not import Blessed. Import it from blessed-components/progress-bar when only string rendering is needed; that subpath keeps the Blessed adapter out of the module graph.

The result has this structure:
```
[label + space][fixed-width track][space][formatted value]
```
Parameters
- options: RenderProgressBarOptions
  Numeric range, track width, characters, and text formatting.
Returns string
A plain terminal string. No ANSI sequences or Blessed tags are added.
Throws
RangeError Thrown when width is not a positive integer.

Throws
RangeError Thrown when min or max is not finite, or when max is not greater than min.

Throws
RangeError Thrown when value is not finite.
Example: Unicode output
```
import { renderProgressBar } from 'blessed-components/progress-bar';

const output = renderProgressBar({
  label: 'Quality',
  value: 78,
  width: 16,
});

// "Quality ████████████░░░░ 78%"
```
Example: ASCII output with a custom value
```
const output = renderProgressBar({
  characters: { filled: '#', empty: '-' },
  formatValue: ({ value }) => `${value} files`,
  label: 'Uploaded',
  value: 25,
  width: 8,
});

// "Uploaded ##------ 25 files"
```
