Add per-model token provider to useReplicatedModels

[Copilot]

When a Vue.js client switches branches, the existing useReplicatedModels would attempt to connect with a stale token, receive a 403, and provide no opportunity for the caller to supply a fresh one. The token provider had no access to model parameters, making repository/branch-scoped tokens impossible.

Changes

useReplicatedModels — new getToken parameter

• Added optional third parameter: getToken?: (params: ReplicatedModelParameters) => Promise<string | null>
• First parameter client now also accepts a server URL string (in addition to ClientJS)
• When client is a URL string and getToken is provided, a dedicated ClientJS is created per model via connectClient(url, () => getToken(params)) — each model gets its own token fetched before the connection is established
• Because the effect re-runs on every models change, getToken is always called with the new params before reconnecting (e.g. on a branch switch)
• Existing ClientJS usage is fully backwards compatible

Usage example

const { rootNodes } = useReplicatedModels(
  "https://my-model-server/v2",
  models,                          // reactive — changes trigger reconnect
  async (params) => fetchToken(params.repositoryId, params.branchId),
);

With multiple models, each receives an independent ClientJS instance and an independently fetched token, so concurrent connections to different repositories/branches with different credentials work correctly.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
