misc/claude-code: New port: Agentic coding tool from Anthropic that lives in your terminal

This is the latest Claude Code CLI that comes only in the binary form.

Previous commit moved previous, NodeJS based claude-code
into claude-code-legacy because of some patches that are there.

Note: Using Claude Code does not strictly require Anthropic's
hosted proprietary models. The tool can interact with open
models via Ollama's Anthropic Messages API compatibility layer.
Users can run these models locally on their own hardware for free,
or utilize Ollama's cloud subscription open weights models for
expanded performance. Some open weights models (like DeepSeek v4 pro)
available via the Ollama cloud are almost as capable as Anthropic's
models for most purposes.
