Multi-threaded state handling, subprocess isolation, extra high thinking, and local model MCP

Release 0.1.7 of the Google Antigravity Python SDK expands end-user control over agent execution environments, strengthens concurrency safety for stateful tools, and introduces deeper reasoning capabilities. Key highlights include atomic multi-threaded state handling for tools and hooks, customizable subprocess environment variable isolation, support for an "extra_high" thinking severity level, and full Model Context Protocol (MCP) and subagent support across local model backends. This release also resolves interactive console prompt clobbering and improves socket discovery under containerized setups.
