Adds Olostep as a tool plugin for Dify agents and workflows.

Olostep is a web data API for AI agents. This plugin gives Dify agents

on a site, run web searches, and get AI-powered answers grounded in live
data — all through 5 ready-to-use tools.

Tools included:

• scrape — Extract markdown, HTML, text or structured JSON from any URL. Handles JS-rendered sites and supports pre-built parsers.
• crawl — Recursively crawl a website with URL filtering and depth control. Returns content from every crawled page.
• map — Discover all URLs on a website from sitemaps and discovered links.
• search — Web search returning ranked results with titles, URLs and descriptions.
• answer — AI-synthesized answer grounded in live web data with source citations. Supports structured JSON output.
