Add 'Debug an auth failure end-to-end' recipe Pattern for diagnosing the most common SDK auth failures: - SDK-version sanity (catches users on the broken 0.4.0-alpha.1) - Token shape sanity (40 chars) - Authenticated probe with branched error handling for UNAUTHORIZED, FORBIDDEN (with IP-allowlist guidance), and the gateway-level 405 'Missing Authentication Token' that alpha.1 produced. Output is meant to be the next action in plain English so a user hitting auth issues knows what to fix without reading the full Authentication wiki page first.

Add Recipes page; add Swift to Sibling SDKs Recipes.md collects ten copyable patterns (backtest polling, fill detection, custom fetch, serverless tuning, etc.). Home now links it from Quick Links. Sibling table updated to add Swift, which was missing from the prose listing and the table.
