 * Resolve an Anthropic alias / canonical ID into a provenance-rich record.
 *
 * Precedence:
 *   1. ENV override `VSKILL_DEFAULT_MODEL_ANTHROPIC` — only when the input is
 *      a plain alias (`opus|sonnet|haiku|best`) so explicit canonical IDs
 *      always win over a tuned default.
 *   2. Catalog lookup — alias OR canonical ID, case-insensitive.
 *   3. Passthrough — unknown future ID; keep the input as `resolvedId`,
 *      record `source: "passthrough"` so the UI can warn about pricing
 *      and the test suite can flag missing entries.
