- Set UTF-8 environment variables (PYTHONUTF8, PYTHONIOENCODING, LANG,
LC_ALL) on all child processes via process.rs helpers
- Configure PTY terminals per shell flavor: chcp 65001 for cmd.exe,
[Console]::OutputEncoding for PowerShell, LANG=C.UTF-8 for Git Bash
- Use /K and -NoExit for interactive shells to avoid nested processes
