dsh-see-world: DSH Decision Layer Plugin

dsh-see-world is a decision-layer plugin for DeepSeek Harness (DSH) that addresses the ambiguity of when an agent should go online and enforces a search-before-answer workflow. It offers features such as zero interruption for local tasks, automatic failure fallback, decision logging, and privacy-friendly design. By default, it follows a strategy of retrieving more rather than missing information, and supports controlling search behavior via message prefixes or natural-language commands. The plugin relies on DSH's search capability layer and is suitable for development scenarios that require strict control over information freshness.
