dsh-write-rule-guard: A DSH Plugin for Intercepting Write Content by Regular Expression Rules

`dsh-write-rule-guard` is a DSH plugin that enforces specific output formats (such as prohibiting full-width brackets). It prevents bypass by intercepting content before writing and disabling the pwsh tool for the current turn. The plugin supports custom regex rules and offers flexible configuration, but a known bypass risk exists once a successful write clears the disabled state.
