DeepSeek Harness Plugin: dsh-reasoning-options - Automatically Populate Reasoning Level and OpenCode Go Routing Header

dsh-reasoning-options is a plugin designed for DeepSeek Harness (DSH), aiming to address issues where third-party gateway models cannot select reasoning levels and the OpenCode Go gateway lacks the Session header. The plugin automatically adds a reasoning intensity selector for all pi-ai models and automatically injects the request headers required by OpenCode Go. It persists configuration through the native API, supports hot reloading, and requires DSH 0.2.0-rc.2 or later.
