FIX 3 van de Windows:

1. LOAD CHAM: PyInstaller onefile 723MB giai nen toan bo vao %TEMP% moi lan chay -> chuyen ONEDIR (engine.spec COLLECT) + bundle qua Tauri resources (resource_dir/daw_engine/daw_engine.exe) thay externalBin — khoi dong tuc thi khong giai nen
2. WINDOW PICKER: Tauri v2 khong co window.__TAURI__.dialog — goi invoke('plugin:dialog|open', {options:{directory:true}}) qua __TAURI__.core.invoke
3. ICON exe: bundle.icon chuyen icon.ico -> favicon.ico + thay 3 PNG bang favicon render
- build_windows.ps1 buoc 4: copy onedir dist/daw_engine -> src-tauri/resources/daw_engine
