Add GitHub Actions workflow for automated Tiny11 ISO building

- Add workflow that downloads Windows ISO, mounts it, and runs builder scripts
- Add automation wrappers for tiny11maker.ps1 and tiny11Coremaker.ps1
- Automatically handle all user prompts (drive letter, image index, .NET 3.5)
- Upload built ISO as artifact
- Add comprehensive mount ISO handling for Windows runner
- Add synchronization documentation

+# Build Flow Synchronization Check
+
+## Workflow → Scripts → Artifact Flow
+
+### 1. Workflow Inputs → Scripts Parameters
+✅ **ISO URL** → Download → Mount → Drive Letter → Passed to scripts as `ISODrive`
+✅ **Script Type** → Routes to correct wrapper script
+✅ **Enable .NET 3.5** → Passed to `run-coremaker-automated.ps1` only
+✅ **Scratch Drive** → Passed to `run-maker-automated.ps1`
+
+### 2. Script Execution Flow
+
+#### tiny11maker flow:
+```
+Workflow (line 190-208)
+  ↓ ISODrive="D:", ScratchDrive=""
+  ↓
+run-maker-automated.ps1
+  ↓ Sets $ISO = "D", $SCRATCH = "" (if provided)
+  ↓ Overrides Read-Host for prompts
+  ↓
+tiny11maker.ps1
+  ↓ Uses $ISO parameter → No drive letter prompt
+  ↓ Still prompts for image index → Auto-answered "1"
+  ↓ Creates ISO at: $PSScriptRoot\tiny11.iso
+```
+
+#### tiny11Coremaker flow:
+```
+Workflow (line 210-217)
+  ↓ ISODrive="D:", EnableDotNet35=false
+  ↓
+run-coremaker-automated.ps1
+  ↓ Fixes $ScratchDisk → $mainOSDrive
+  ↓ Overrides Read-Host for all prompts
+  ↓
+tiny11Coremaker.ps1
+  ↓ Prompts for drive letter → Auto-answered
+  ↓ Prompts for image index → Auto-answered "1"
+  ↓ Prompts for .NET 3.5 → Auto-answered from parameter
+  ↓ Creates ISO at: $PSScriptRoot\tiny11.iso
+```
+
+### 3. ISO Output Location
+
+**Scripts create ISO at:**
+- `$PSScriptRoot\tiny11.iso` (repo root)
+
+**Workflow looks for ISO at:**
+- `$PSScriptRoot\tiny11.iso` (repo root)
+- ✅ **SYNCHRONIZED**
+
+### 4. Path Resolution
+
+**Wrapper Scripts:**
+- `$PSScriptRoot` in wrapper = `.github\scripts\`
+- `$scriptRoot = Split-Path -Parent (Split-Path -Parent $PSScriptRoot)` = repo root
+- ✅ **CORRECT**
+
+**Scripts called:**
+- `tiny11maker.ps1` uses `$PSScriptRoot` = repo root (when called from wrapper)
+- `tiny11Coremaker.ps1` uses `$PSScriptRoot` = repo root (when called from wrapper)
+- ✅ **SYNCHRONIZED**
+
+### 5. Variable Fixes
+
+**tiny11Coremaker.ps1:**
+- Line 559: Uses `$ScratchDisk` → Fixed in wrapper to `$mainOSDrive`
+- ✅ **FIXED**
+
+**tiny11maker.ps1:**
+- Uses `$ScratchDisk` parameter → Correct
+- ✅ **OK**
+
+### 6. Artifact Upload
+
+**Workflow:**
+- Finds ISO → Sets `ISO_PATH` env var
+- Uploads using `${{ env.ISO_PATH }}`
+- ✅ **SYNCHRONIZED**
+
+## Verification Checklist
+
+- [x] Workflow mounts ISO correctly
+- [x] Workflow passes drive letter correctly (with ":")
+- [x] Wrapper scripts handle drive letter correctly (remove ":")
+- [x] Wrapper scripts fix $ScratchDisk issue
+- [x] All prompts are auto-answered
+- [x] ISO output path matches between scripts and workflow
+- [x] Artifact upload path is correct
+- [x] Cleanup properly unmounts ISO
+
+## Status: ✅ ALL SYNCHRONIZED

+# GitHub Actions Workflow - Build Tiny11 ISO
+
+Workflow này tự động hóa quá trình tạo Windows 11 tiny image bằng GitHub Actions.
+
+## Cách sử dụng
+
+1. **Chuẩn bị Windows 11 ISO URL**
+   - Bạn cần có link download Windows 11 ISO (ví dụ: từ Microsoft hoặc các nguồn khác)
+   - Link phải hỗ trợ direct download
+
+2. **Chạy workflow**
+   - Vào tab **Actions** trong repository
+   - Chọn workflow **Build Tiny11 ISO**
+   - Click **Run workflow**
+   - Điền các thông tin:
+     - **iso_url**: Link download Windows 11 ISO
+     - **script_type**: Chọn `tiny11maker` hoặc `tiny11Coremaker`
+     - **enable_dotnet35**: Bật/tắt .NET 3.5 (chỉ cho Core)
+     - **scratch_drive**: Drive letter cho scratch disk (để trống sẽ dùng script root)
+
+3. **Chờ quá trình build**
+   - Workflow sẽ tự động:
+     - Download Windows ISO
+     - Mount ISO
+     - Chạy script build
+     - Tạo ISO file
+     - Upload artifact
+
+4. **Download ISO**
+   - Sau khi build xong, vào tab **Actions**
+   - Click vào run vừa hoàn thành
+   - Scroll xuống phần **Artifacts**
+   - Download file `tiny11-iso`
+
+## Lưu ý
+
+- Workflow chạy trên Windows runner và có thể mất 60-180 phút
+- Runner cần có đủ dung lượng để xử lý ISO (khuyến nghị ít nhất 50GB free space)
+- Script sẽ tự động trả lời các prompts trong quá trình build
+- ISO sẽ được giữ trong 7 ngày sau khi upload
+
+## Script Types
+
+### tiny11maker
+- Script chính, giữ lại khả năng service (có thể thêm language, update sau)
+- Khuyến nghị cho sử dụng thông thường
+
+### tiny11Coremaker  
+- Script Core, loại bỏ nhiều thành phần hơn
+- Không thể service sau khi tạo (không thể thêm language, update)
+- Chỉ khuyến nghị cho testing/development
+
+## Troubleshooting
+
+- Nếu workflow fail ở bước mount ISO: Kiểm tra lại link download có hợp lệ không
+- Nếu không tìm thấy ISO sau build: Kiểm tra logs để xem script có chạy thành công không
+- Nếu hết thời gian: Tăng timeout trong workflow (mặc định 180 phút)
