Agent2 v0.3.0

Agent2 v0.3.0 — CLI Onboarding & Brain Clone Harness

Added

• First-class agent2 CLI with setup, onboard, doctor, list, run, serve, and publish-check commands
• Static installer scripts for macOS/Linux and Windows
• Agentic Brain Clone onboarding harness — LLM-powered adaptive interview that extracts domain expertise and generates a complete agent
• Step-by-step questionary setup wizard with model selection, profile choice, and Docker configuration
• Textual TUI alternative for fullscreen onboarding
• Central agent2.yaml framework configuration for default model, provider policy, stack profile, telemetry, and ports
• ASCII art banner in installer
• TTY detection for piped install with graceful fallback

Changed

• Normal agent configs now use model: "" and resolve through global framework config
• Docker agent images copy agent2.yaml so global config is available in containers
• Model resolution order: explicit runtime arg > agent config > agent2.yaml > env fallback
