feat: add olostep-web-research experimental skill

Summary

Adds a new experimental skill for web research using the Olostep API. Enables agents to scrape URLs, crawl websites, perform web searches, and synthesize research answers from live web data.

Changes

• SKILL.md — Skill definition with authentication guidance and CLI interface documentation
• scrape.py — Python script for scraping individual URLs with format options (markdown, text, html, json)
• api_docs.md — Quick reference for Olostep API endpoints, parameters, and response formats
• requirements.txt — Dependencies (olostep>=1.0.0)

Usage

Users can enable this skill in Codex by setting their API key:

export OLOSTEP_API_KEY='your_key'

Then invoke via:

• scrape.py --url <url> — Extract content from a single page
• crawl.py --url <url> — Crawl multiple pages from a site
• search.py --query "<query>" — Perform web search
• answer.py --task "<question>" — AI-synthesized answer with sources

Auth Pattern

Follows the same secure pattern as render & imagegen skills: API key required as environment variable, never stored in the skill itself.
