Automagically connect scrcpy wirelessly on windows

- [X] I have read the [FAQ](https://github.com/Genymobile/scrcpy/blob/master/FAQ.md).
- [X] I have searched in existing [issues](https://github.com/Genymobile/scrcpy/issues).

**Environment**
- OS: Windows
- scrcpy version: 1.12.1+
- installation method: amy
- device model: any
- Android version: any

**Describe the bug**
Not a bug, but a possible solution for using scrcpy wirelessly
Getting scrcpy connect to android phone wirelessly it's not too easy. With the below windows script after attaching your phone with usb for one time everything works until you restart you're phone.

My primary use case is: Enable tethering on phone, attach pc to this wifi, connect phone via USB to PC, run script. After this is done, running script should connect via wifi without USB connection.

(script it's not really readable, let me know if you have problems using it.)
`echo off
set %ADBPath=
rem set ADBPath=C:\Programs\scrcpy1.21\
rem echo %cd%

setlocal EnableDelayedExpansion
setlocal EnableExtensions

rem to clear local variable and registry use following instructions from command prompt
rem set AndroidIPLocal=
rem reg add "HKCU\Volatile Environment" /v "AndroidIP"

echo This script will try to connect your phone with this computer via Scrcpy over wifi! Modify ADBPath to match adb and scrcpy directory (they must be on same dir)
%ADBPath%adb version

rem echo argument %1
echo reading saved phone ip from registry...
for /f "tokens=3" %%i in ('reg query "HKCU\Volatile Environment" /v "AndroidIP" ') do (set AndroidIPLocal=%%i)

Start with FAQ.md and the supplied Windows batch script, which uses adb and scrcpy to discover the device and connect over Wi‑Fi. The issue names no repository file or test; done would be a clearly supported Windows workflow that automates the described wireless connection after USB setup.
