glyVisual file system formatting for PowerShell

Add configurable glyphs and colors to FileInfo and DirectoryInfo output without replacing the PowerShell object pipeline.

PowerShell-native

Uses PowerShell format data for the standard FileInfo and DirectoryInfo table view.

Preserves input objects and keeps Get-ChildItem and Get-Item semantics unchanged.

Supports session themes, glyph sets, renderer selection, and explicit plain-text fallback.
