adb commands spawn unnecessary console windows constantly

[zspandy]

Description

On Windows, when using agent-device, every command (such as snapshot, press, fill, etc.) frequently pops up an adb command line window. These windows flash briefly and disappear, severely impacting the user experience and interfering with automation workflows.

Steps to Reproduce

1. Install agent-device on Windows
2. Connect to an Android emulator or real device
3. Execute any command, e.g., agent-device snapshot -i
4. Observe the screen — an adb.exe command line window pops up and closes immediately

Expected Behavior

adb commands should run silently in the background without popping up console windows.

Actual Behavior

Each adb invocation spawns an independent console window.

investigating. I don't have a windows machine, but will see what we can do. I may ask you to test the PR once sent 🙏🏼
