Add Windows compatibility with native batch and PowerShell scripts

[Copilot]

This PR addresses the Windows compatibility concern raised in the issue. The repository previously only provided a bash script (build_test.sh) for build automation, which doesn't work natively on Windows systems.

Changes Made

New Windows Scripts

• build_test.bat - Native Windows Command Prompt script with identical functionality to the bash version
• build_test.ps1 - PowerShell script with enhanced colored output and better error handling

Both scripts provide the same build testing, hardware setup instructions, and pairing guidance as the original bash script.

Enhanced Documentation

• docs/WINDOWS_SETUP.md - Comprehensive Windows setup guide covering:
  • Installation of required software (Git, Python, VS Code)
  • PlatformIO setup via VS Code extension or command line
  • Windows-specific troubleshooting (COM ports, USB drivers, PowerShell execution policies)
  • Alternative Arduino IDE setup instructions

Updated Existing Documentation

• README.md - Added Windows-specific build instructions and troubleshooting sections
• arduino_ide_version/README_Arduino.md - Enhanced with Windows library paths and setup notes

Usage Examples

Windows Command Prompt:

build_test.bat

PowerShell:

.\build_test.ps1

Cross-platform PlatformIO:

pio run --target upload

The solution maintains backward compatibility while providing native Windows support. All three script variants (.sh, .bat, .ps1) produce identical output and functionality.

Fixes #4.
