Function VDivider

VDivider(props?: VDividerProps): ContainerNode
Vertical divider that fills the available height.

Renders a single character on each row within a 1-cell-wide container. Best used inside an HStack to separate columns.

The container uses height: "100%" so it fills the parent's cross axis. In an HStack with the default alignItems: "stretch", it automatically matches sibling heights.
Parameters
- props: VDividerProps = {}
  Divider character and color.
Returns ContainerNode
A container node 1 cell wide, full parent height.
Example
```
// Default thin vertical line
VDivider()

// Double line with color
VDivider({ char: "║", fgColor: "color08" })

// Separate sidebar from content
HStack({ height: "100%" }, [
  VStack({ width: 20 }, [Text("sidebar")]),
  VDivider({ fgColor: "color08" }),
  VStack({ flex: 1 }, [Text("content")]),
])
```
