Earendil ships Pi 1.0 agent harness with MCP support by default

Pi 1.0 adds Codemode (native MCP support plus non-LLM models like Jev and image models), deferred tool loading, Anthropic cache warming, and full-screen mode by default. Earendil says hundreds of thousands of people use Pi weekly; an experimental Pi Durable package for long-running agents ships alongside it.
