/**
 * Normalize a `decision_model` string into a `{ provider, model }` pair for the
 * OpenClaw `llm-task` call.
 *
 * Background: OpenClaw builds the final model identity as `provider + "/" + model`.
 * The provider comes from `agents.defaults.model.primary` (set by the railway
 * template), and the model from this plugin. If the YAML's `decision_model`
 * ALREADY carries a provider prefix (e.g. `google/gemini-3.1-pro-preview`) and we
 * forward it verbatim, OpenClaw v2026.2.22 glues it again →
 * `google/google/gemini-3.1-pro-preview` → "Unknown model". (v2026.5.7+ added a
 * de-dup, but prod boxes run v2026.2.22.)
 *
 * Fix: if the model contains a `/`, split on the FIRST slash and send the leading
 * segment as an explicit `provider` plus the remainder as a bare `model`. OpenClaw
 * then re-glues `provider + "/" + model` to the intended key with no duplication —
 * correct on v2026.2.22 AND a harmless no-op on v2026.5.7+ (the de-dup sees a bare
 * model). A bare input (no slash) is returned as model-only, so OpenClaw fills the
 * provider from `primary` as before.
 *
 * First-slash splitting also preserves aggregator ids:
 * `openrouter/google/gemini-3.1-pro-preview` → provider `openrouter`, model
 * `google/gemini-3.1-pro-preview`.
 *
 * Defensive edges (no provider extracted, returned as model-only): empty/undefined
 * input, leading slash (`/foo`), trailing slash (`foo/`).
