dsh-bash-terminal: Unifying PowerShell, Git Bash, and WSL Shell Tools on Windows

dsh-bash-terminal is a DSH community plugin maintained by MAXeaglet, providing additional shell and terminal tools on Windows. Users set the default terminal (PowerShell, Git Bash, or WSL) via the Web UI, which is automatically used as the backend for model command execution and cannot be switched manually. The shell starts a fresh process each time, suitable for one-off commands, while the terminal maintains the current working directory and variables across rounds, ideal for interactive CLI. The plugin integrates with DSH's official sandbox and background task mechanisms without occupying the official pwsh tool. Installation requires global npm installation and running the install.ps1 patch to set up the whitelist.
