Harness/DSH Third Party Model Session Sandbox

Key features

• This plugin makes DeepSeek Harness show the model only the sandbox escalation options that the current session can actually use.
• dsh-sandbox-escalation-fix is a zero-configuration compatibility plugin that directly resolves the issue of third-party models like GPT failing to call tools such as bash, pwsh, write, and edit under DSH All Access, resulting in repeated retries due to incorrect sandbox escalation parameter prompts.
• Models still see and send sandbox_permissions / justification in All Access sessions, so tools fail before they run.
• Native tool schemas omit impossible escalation fields
• In an All Access session (danger-full-access + never), the stock DSH tools still advertise sandbox_permissions and justification on bash, pwsh, write, and edit.
