/**
 * OpenRouter Provider Adapter
 *
 * Implements the unified ILLMProvider interface for OpenRouter's API.
 * OpenRouter provides an OpenAI-compatible chat completions API at
 * https://openrouter.ai/api/v1, with required HTTP-Referer and X-Title
 * headers for attribution.
 *
 * Models use provider-prefixed format (e.g., "anthropic/claude-sonnet-4",
 * "openai/gpt-4o", "google/gemini-2.0-flash"). The default model for
 * HoloScript generation is "anthropic/claude-sonnet-4" — a strong generalist
 * that balances cost and capability.
 *
 * @version 1.0.0

/**
 * Capability manifest — OpenRouter is a meta-provider whose actual
 * capabilities depend on the upstream model selected. Conservative
 * declaration: only what's universally true across the catalog.
 *
 * For routing decisions that need specific model superpowers, prefer
 * the direct provider adapter (Anthropic / OpenAI / etc.) — OpenRouter
 * is the fallback / cost-shopping path, not the capability-sensitive
 * default. `costPerMillion` omitted (varies wildly per upstream).
 *
 * Exported as a constant so the capability-aware router can read it
 * without instantiating the adapter — single source of truth per W.GOLD.006.
