dsh-subagent-model: DSH Plugin for Per-Call Model Routing and Context Inheritance

dsh-subagent-model is a DSH plugin maintained by Momojie-S and based on @deepseek-ai/dsh-tool-subagent, providing the subagent_model tool to enhance subagent delegation capabilities. Its core features include dynamically specifying provider, model, and max_tokens for each call, and flexibly controlling context via the fresh_context parameter: a clean context is enabled when the parameter is omitted or set to true, while passing false inherits the current conversation based on the latest state of the parent session at the time of the call. The plugin supports background execution, distinguishes between continuable (sustainable interaction) and one-shot (one-time task) strategies, and prioritizes routing based on call parameters over the plugin.
