refactor(open-sse): D1a/D1b — URL quirks → schema urlSuffix + clean debug logs

buildUrl: switch provider-name → config-driven. ?beta=true thành
urlSuffix per registry (claude/glm/kimi/minimax/minimax-cn/kimi-coding);
gemini path dùng format==="gemini"; accountId substitution giữ generic.
Xóa console.log('[DEBUG]') trong refreshCline.
Golden url-header 142 pass (byte-for-byte URL).
