DSH WeNeed Plugin: Inject WeNeed Thinking Seed Before DeepSeek Flash Request

dsh-we-need-plugin (0.7.1) is a DSH Host plugin maintained by Lichadai. It inserts the assistant seed from `seed.txt` into the stream layer before the last real user task, making requests with upstream model IDs containing both "deepseek" and "flash" more likely to trigger "We need/Let's" style plan reasoning. When using delegated mode, it does not alter the provider, API key, or sampling parameters; the seed is written to both `content` and `reasoning_content` but is not added to the conversation history. Installation requires DSH >= 0.2.2-rc.1, and DSH must be fully restarted after installation. It provides probabilistic guidance and must be used in conjunction with "tool after call" and context simplification.
