Start a scoped full-site crawl with Firecrawl, by explicit rules or natural-language prompt (POST /v2/crawl)

Documented steps

1. AUTH: Authorization: Bearer fc-YOUR_API_KEY; base URL https://api.firecrawl.dev/v2
2. POST https://api.firecrawl.dev/v2/crawl with minimal body {"url": "https://example.com"}
3. Scope it: {"url":"https://example.com","limit":500,"includePaths":["^/docs/.*"],"excludePaths":["^/blog/.*"],"maxDiscoveryDepth":3,"sitemap":"include","crawlEntireDomain":false,"allowExternalLinks":false,"allowSubdomains":false}
4. Or use prompt-based config: {"url":"https://example.com","prompt":"Crawl only the API reference and docs pages, skip the blog"} — Firecrawl derives the scoping options
5. Preview what a prompt resolves to before committing: POST /v2/crawl/params-preview with the same body
6. Optionally add scrapeOptions (e.g. {"formats":["markdown"]}) and a webhook object in the same request
7. Response: {"success":true,"id":"<crawl-uuid>","url":"https://api.firecrawl.dev/v2/crawl/<crawl-uuid>"} — keep the id for status polling
