 * Normalize an Anthropic-API-style Claude model ID to the Vertex publisher

 * The Anthropic API dates models with a trailing dash segment

 * with "@" ("claude-haiku-4-5@20251001"). Vertex rejects the dash form with a
 * 404 (verified live against us-east5), so the native Vertex+Claude paths
 * normalize before calling @anthropic-ai/vertex-sdk.
 *
 * Pass-through cases: IDs already in "@" form, bare aliases with no date
 * ("claude-sonnet-4-6" — Vertex resolves these itself), and non-Claude models.
 * Legacy v2-suffixed Vertex IDs ("claude-3-5-sonnet-v2@20241022") have no
 * dash-date equivalent, so those legacy dash IDs stay out of scope: they 404
 * today and still 404 after the transform — no regression either way.
