Extract version parsing to shared function and improve error handling

- Created Get-VersionChangeType function in scripts/utils.ps1 (DRY principle)
- Updated vendor.yml and update.ps1 to use shared function
- Fixed numeric comparison for COUNT_UPDATED (fromJSON for proper numeric eval)
- Improved git operation error handling with proper exit code checking
- Only reset commit if it succeeded but push failed

+    .SYNOPSIS
+    Analyzes version changes using semantic versioning to determine the type of update and appropriate emoji.
+    
+    .DESCRIPTION
+    Parses old and new version strings, compares them using semantic versioning rules,
+    and returns information about the change type, emoji indicator, and whether it's a major update.
+    
+    .PARAMETER OldVersion
+    The previous version string (e.g., "1.2.3" or "2.52.0.windows.1").
+    
+    .PARAMETER NewVersion
+    The new version string (e.g., "1.3.0" or "3.0.0.windows.1").
+    
+    .OUTPUTS
+    Returns a hashtable with the following keys:
+    - ChangeType: "major", "minor", "patch", "downgrade", or "unknown"
+    - Emoji: The corresponding emoji indicator (🔥, 🚀, ⬆️, or 🔄)
+    - IsMajor: Boolean indicating if this is a major version update
+    
+    .EXAMPLE
+    $result = Get-VersionChangeType -OldVersion "1.2.3" -NewVersion "2.0.0"
+    # Returns: @{ ChangeType = "major"; Emoji = "🔥"; IsMajor = $true }
+    
+    .EXAMPLE
+    $result = Get-VersionChangeType -OldVersion "1.2.3" -NewVersion "1.3.0"
+    # Returns: @{ ChangeType = "minor"; Emoji = "🚀"; IsMajor = $false }
