+- **fix(cli):** OpenCode config generator preserves catalog display names — custom names win, then `display_name`/native `name` (with the `owned_by/` prefix stripped once), then a readable label for `auto/*` ids, instead of always showing the raw model id ([#13168](https://github.com/diegosouzapw/OmniRoute/pull/13168)) — thanks @domenicomassafra

+/**
+ * Regression guard for #13168: the OpenCode config generator used to emit
+ * the raw catalog model id as the display name, so `auto/chat` stayed
+ * `auto/chat` and provider-prefixed catalog labels duplicated the provider
+ * name. `buildModelEntry()`'s name precedence (highest to lowest) is:
+ *   1. an existing custom name already set by the user in opencode.json
+ *   2. a readable label for `auto/*` ids (OmniRoute's own virtual routing ids)
+ *   3. the catalog's `display_name` (falling back to `name`), with a leading
+ *      `owned_by/` prefix stripped once
+ *   4. the raw catalog/model id, when nothing else is known
