Replace VSCode extension impersonation (client ID Iv1.b507a08c87ecfe98,
User-Agent GitHubCopilotChat/0.35.0) with the opencode OAuth app
(Ov23li8tweQw6odWQebz, User-Agent opencode/1.3.15).

the oauth module

and openai-compat.ts (resolveGitHubCopilotBaseUrl now passes through
the model baseUrl unchanged)
