/**
 * `/workflows-models` command handler — the role-routing editor (issue #142).
 *
 * Uses Pi's built-in `ctx.ui.select()`, `ctx.ui.confirm()`, and `ctx.ui.notify()`
 * to let users view and manage model routing configuration for workflows.
 *
 * The primary surface is the semantic role layer (worker / conductor / advisor /
 * security), each with a default model and optional named specialist routes
 * (e.g. escalation, long-context, independent). A clearly-marked legacy-tier
 * migration section (small/medium/big) is preserved for compatibility — size
 * tiers are accepted only as deprecated migration inputs.
 *
 * Model selection draws from the same `listAvailableModelSpecs()` that powers
 * Pi's `/model` command, so users see exactly the same models.
