Adds `WebsiteBrandingService` (OSS) with an Enterprise override using
Firecrawl v2 to extract branding and business data from a URL for
onboarding auto-fill.
OSS version uses HTTParty + Nokogiri to extract:
- Business name (og:site_name or title)
- Language (html lang)
- Favicon
- Social links from `<a>` tags
Enterprise version makes a single Firecrawl call to fetch:
- Structured JSON (name, language, industry via LLM)
- Branding (favicon, primary color)
- Page links
Falls back to OSS if Firecrawl is unavailable or fails.
Social handles (WhatsApp, Facebook, Instagram, Telegram, TikTok, LINE)
are parsed deterministically via a shared `SocialLinkParser`.
> We use links for socials, since the LLM extraction was unreliable,
mostly returned empty, and hallucinated in some rare scenarios
## How to test
```ruby
# OSS (no Firecrawl key needed)
WebsiteBrandingService.new('chatwoot.com').perform
# Enterprise (requires CAPTAIN_FIRECRAWL_API_KEY)
WebsiteBrandingService.new('notion.so').perform
WebsiteBrandingService.new('postman.com').perform
```
Verify the returned hash includes business_name, language,
industry_category, social_handles, and branding with
favicon/primary_color.
