/**
* `@deepseek-ai/dsh-web-search-perplexity`: registers a Perplexity-backed
* `WebSearchProvider` with `ctx.web`. A function/namespace plugin (NOT a
* default-export service): it registers INTO the seam's provider registry, like
* `@deepseek-ai/dsh-llm-deepseek` registers an adapter into `ctx.llm`.
*
* @module @deepseek-ai/dsh-web-search-perplexity
