[Feature Request] Merge NTLite and Winhance autounattend.xml configurations

Problem

When using both NTLite and Winhance, each tool generates a complete autounattend.xml. Manual merging is error-prone because:

• NTLite configures language settings (e.g., zh-CN) that should be preserved
• Winhance embeds PowerShell scripts in <Extensions> node that cannot be simply copy-pasted
• Multi-architecture components (x86/arm64/amd64) are easy to miss

Desired Solution

Option A: Incremental Export

• Export only Winhance optimization snippets (without base settings)
• User merges into existing NTLite XML

Option B: One-Click Merge Tool

Input:  NTLite_autounattend.xml + Winhance_autounattend.xml
Output: Merged_autounattend.xml

Rules:
- Keep NTLite International-Core (language/region settings)
- Keep NTLite empty ProductKey
- Merge Winhance OOBE optimizations
- Inject Winhance <Extensions> PowerShell scripts
- Auto-handle x86/arm64/amd64 components

Use Case

After creating a slimmed image with NTLite, automatically apply Winhance optimizations during Windows setup without running Winhance manually on each machine.

Key Requirements

Keep from NTLite	Add from Winhance
Language/region settings	Hardware bypass checks
Empty ProductKey	System optimization scripts
Base OOBE config	Services/privacy/performance tweaks
	FirstLogonCommands

---

Use case

When creating a system image with NTLite, Winhance optimization settings can be integrated simultaneously.
