A DeepSeek Harness host plugin that removes invalid sandbox_permissions and
justification arguments before native tool dispatch.

Problem Solved

Some models or OpenAI-compatible gateways include every advertised optional
argument in ordinary pwsh, write, or edit calls. When the injected
sandbox_permissions equals the session's current mode, or is narrower, DSH
correctly rejects the call before it runs with an error such as:

sandbox escalation to "workspace-write" is not strictly wider than this call's current "workspace-write" mode

The same failure occurs in a danger-full-access session when the model still
sends either advertised escalation mode. This is not a real sandbox denial;
the session already has sufficient access, but the invalid escalation fields
prevent the intended tool call from executing.

It only removes a request when it is not strictly wider than the calling
session's effective sandbox mode. Valid escalation requests remain unchanged
and continue through DSH's normal approval flow.

Examples:

• workspace-write session + sandbox_permissions: workspace-write: removed.
• danger-full-access session + either advertised mode: removed.
• read-only session + sandbox_permissions: workspace-write: preserved for
  the regular approval flow.

The plugin hooks the tools/execute waterfall. It does not auto-approve
requests and does not alter session permission state.
