Issue Description

The extension matching logic in Get-ChangedFilesWithExtensions function is broken and will cause incorrect behavior.

File: scripts/linting/Modules/LintingHelpers.psm1
Line 62

Problem

Current code:

$matchesExtension = $FileExtensions | Where-Object { $_ -like $_ } | ForEach-Object { $file -like $_ } | Where-Object { $_ } | Select-Object -First 1

• \$_ -like \$_ always evaluates to true
• \$file variable is undefined in this scope (should be \$_ from parent pipeline)

Expected Fix

$matchesExtension = $false
foreach ($pattern in $FileExtensions) {
    if ($_ -like $pattern) {
        $matchesExtension = $true
        break
    }
}

Impact

• Severity: Critical
• Function will fail or produce incorrect results when filtering files by extension
