Cline CLI 3.0.52: queued-prompt and MCP durability fixes from SDK 0.0.72

Adds `cline mcp uninstall` and lets schedules inherit saved provider settings. The bulk is reliability work inherited from SDK v0.0.72: interrupted turns no longer silently drop queued prompts, a hung MCP server no longer blocks session creation, and LiteLLM traffic moves to Chat Completions so proxy setups work.
