DeepSeek Harness (DSH) Plugin: dsh-sxs-anti-bot-http Anti-Scraping HTTP Tool

`dsh-sxs-anti-bot-http` is an HTTP request utility designed specifically for the DSH plugin ecosystem to address anti-bot and rate-limiting challenges. Built on the SXS data-collection framework and developed by user yangyunsong023, it is implemented in pure Node.js with zero runtime dependencies. Its core features include user-agent pool rotation, exponential-backoff retries, anti-bot wall detection, and site-level adaptive rate limiting. Developers can install it easily by specifying a Git link and use functions such as `sxs_fetch` and `sxs_fetch_json` to perform stable data scraping for DSH agent online-capability development.
