DeepSeek Harness Plugin: bottledkzk/dsh-search-router (Multi-Provider Search Routing with Automatic Failover)

`dsh-search-router` is a network-enabled tool plugin within the DSH ecosystem, designed to address the lack of resilience in single search engine interfaces. It supports multiple providers and offers real-time switching, status monitoring, and automatic failover. If the primary provider becomes unavailable, it automatically falls back to a backup source. Currently, users need to obtain and integrate the source code themselves. Since it runs with process privileges and involves network requests, it is recommended to validate its logic in a test environment first.
