feat: add modelNameDisplay option to show model id instead of name

[Rahulsharma0810]

Problem

The plugin renders model.name in the OpenCode model picker (plugin.ts:789). When multiple OmniRoute providers serve the same base model, they all return the same name value — e.g. four providers all return name: "GPT-5.5" for their respective gpt-5.5 entry.

This leaves the user with a picker full of identical display names and no way to tell which provider they are selecting.

Proposed fix

Add a modelNameDisplay option to OmniRouteConfig:

Value	Display name shown
"name" (default)	name field from /v1/models — unchanged behaviour
"id"	id field from /v1/models — always unique per entry

When set to "id", the picker shows "gh/gpt-5.5", "cx/gpt-5.5" etc., making all entries distinguishable regardless of the server-side name.

Usage

// opencode.js
import OmniRouteAuthPlugin from 'opencode-omniroute-auth';

export default {
  plugins: [OmniRouteAuthPlugin],
  provider: {
    omniroute: {
      options: {
        baseURL: 'http://localhost:20128/v1',
        modelNameDisplay: 'id',   // show "gh/gpt-5.5" instead of "GPT-5.5"
      },
    },
  },
};

Relationship to server-side fix

A complementary server-side fix (diegosouzapw/OmniRoute#4516 / diegosouzapw/OmniRoute#4517) qualifies ambiguous model names on the server. The client-side option is still useful for older OmniRoute versions or when the user prefers raw IDs unconditionally.
