wip/neo 0.6.2 NetBSD

Neo is an AI-powered coding agent that turns complex repository work into a visible workflow. It keeps the plan, tools, tests, reviews, and delivery moving in one terminal.

Features:

• Visible by default: see the plan, active work, tool activity, tests, and delegated tasks without reading a wall of chat
• One coordinator, focused workers: delegate bounded work to sub-agents and bring their evidence back into one coherent workflow
• Multiple model backends: Anthropic, OpenAI, Google Gemini, or OpenRouter
• Granular permissions: trusted, approval-based, or read-only
• Single Go binary with built-in tools, local sessions, no runtime or plugin stack
