Add sync-openrouter: slug-keyed OpenRouter alternates for carried models

Mirrors the Bedrock/Baseten pattern: OpenRouter serves many models we already
carry under a different `<vendor>/<model>` slug (e.g. openrouter `x-ai/grok-4.5`
== our `grok-4.5`). Rather than union `openrouter` onto the canonical entry, this
creates a SEPARATE entry keyed by the openrouter slug, `format: "openai"`,
`available_providers: ["openrouter"]`, with pricing/context/modality/reasoning
pulled from OpenRouter's public /api/v1/models directory.

- sync_models.ts: OpenRouter schemas + fetch, `openRouterCanonicalId` (strip
  vendor prefix, reject :variant slugs), `convertOpenRouterToLocalModel`,
  `applyOpenRouterPricing`, and `syncOpenRouterModelsCommand`. Bounded to models
  we already carry; openrouter-only models and :free/:nitro variants are skipped.
  Existing non-openrouter entries that share a slug (e.g. the multi-provider
  `openai/gpt-oss-120b`) are never touched.
- Registered as the `sync-openrouter` yargs command.
- sync-models.yaml: daily "Sync OpenRouter alternates" step (public endpoint,
  OPENROUTER_API_KEY optional).
- Tests for the canonical-id strip, converter, and pricing refresh.
- Generates 86 slug-keyed alternates (openai, google, mistralai, perplexity,
  x-ai, cohere, anthropic, microsoft) + their index.ts ["openrouter"] mappings.

Routing note: the deployed Rust gateway (lingua) does not yet implement the
`openrouter` provider kind (router_builder returns "unsupported provider kind"),
so these resolve + find the org secret but cannot invoke until lingua adds it.
The catalog entries are correct regardless; routing needs that gateway change.
