feat: add v2 documentation with versioned navigation and updated SDKs

Migrate documentation to v2 structure with versioned nav (v2 default, v1 legacy).
Update Python and JavaScript SDK docs to reflect v2 API changes (extract, search,
scrape, crawl, monitor namespaces, FetchConfig/LlmConfig). Add v1/ legacy pages
with deprecation banners.
