Fix Get-GitRepoRoot type inconsistency causing empty string return from subdirectories

[Copilot]

The Get-GitRepoRoot function had a type inconsistency bug that returned an empty string when executed from subdirectories, though it worked correctly from the repository root.

Root Cause

Get-Location returns a PathInfo object, while Split-Path returns a string. After the first loop iteration:

$currentPath = Get-Location              # PathInfo object
$parentPath = Split-Path $currentPath    # String
$currentPath = $parentPath               # Now a string

When .git is found in a subsequent iteration, return $currentPath.Path attempts to access the .Path property on a string, which returns an empty string instead of failing.

Changes

• Initialize $currentPath as a string: $currentPath = (Get-Location).Path
• Return $currentPath directly instead of $currentPath.Path
• Maintains type consistency throughout the loop

This ensures the function returns the correct repository root path regardless of the working directory depth.
