Documentation overhaul
Completely restructured the API documentation into 8 dedicated sub-pages for easier navigation: Getting Started, Capture Options, Page Interaction, Content Injection, Output Settings, Caching & Webhooks, Batch API, and Signed URLs. Each page now includes multi-language code examples in cURL, Node.js, Python, PHP, Go, Java, and Ruby with one-click tab switching.
Added collapsible sidebar navigation with subsection groups so you can quickly jump to the parameter you need. Fixed incorrect response field names in code examples, escaped HTML entities, and added the reduced_motion parameter to the docs.
