Cline SDK 0.0.67: catalog-driven reasoning controls, session forking API, MCP timeout config

Reasoning effort/budget is now normalized from the models.dev catalog before provider encoding, with out-of-range budgets clamped and Anthropic's mandatory/impossible thinking modes handled explicitly. Adds session forking and user-run message APIs so a host can edit an earlier prompt, and honors the per-server MCP `timeout` (default 60s, clamped 1–3600s) instead of hardcoded 1.5s/5s limits. The OpenAI Compatible provider's "Enable R1 messages format" option was removed and OpenRouter's default model is now `anthropic/claude-sonnet-5`.
