Fix Windows executable and update environment dependencies

[XingjiaYang]

Summary

This PR addresses two main issues:

1. Windows executable fix

   • Rebuilt the Windows .exe with PyInstaller.
   • Fixed missing package metadata issues for readchar, inquirer3, blessed, and pymobiledevice3.
   • Suppressed unnecessary blessed terminal warnings (ssupm) on Windows.
   • Verified that the executable launches correctly and reaches the app selection prompt.

2. Environment dependency update

   • Pinned all major dependencies in requirements.txt to fixed versions for reproducible builds.
   • Excluded platform-incompatible packages (uvloop, lzfse, sslpsk-pmd3) on Windows.
   • Added explicit instructions to use Python 3.12.3 with .venv, and not to use modern environment managers such as uv or conda.

Changes

• Updated requirements.txt with pinned versions and platform-specific exclusions.
• Updated README/Usage instructions to specify Python version and .venv workflow.
• Rebuilt TrollRestore.exe for Windows.

Notes

• Users can now run the Windows executable directly without installing Python.
• Developers should use .venv with Python 3.12.3 to reproduce builds.
• The blessed warning about ssupm is suppressed and does not affect functionality.
