dsh-bash-native: A Native POSIX Bash Executor for Windows

`dsh-bash-native` is a DSH plugin developed by SpookyWaste, designed to provide a native POSIX bash execution environment on Windows. Written in Rust, it does not depend on WSL or MSYS, and supports native binary execution, three-tier permission policies, background jobs, and persistent terminals. Installation requires DSH >= 0.2.0-rc.2, Node >= 22.12.0, and Windows x64, and requires enabling the Native Bash preset and persistence components in settings. The plugin is suitable for scenarios that require native environment automation.
