feat(provider): add CodeBuddy CN provider (copilot.tencent.com)

Add Tencent CodeBuddy CN (codebuddy-cn) OAuth provider with full support: OAuth login (GET poll with state query param), token refresh, 15-model catalog, /v2 inference endpoint, forced streaming, OpenAI-style reasoning, and per-model capabilities. Renamed from codebuddy to codebuddy-cn to allow a future codebuddy-ai variant. Co-authored-by: Cursor <cursoragent@cursor.com>
