Ollama adds Claude Code support

This is a quietly important interoperability win: Ollama is turning Anthropic-native agent tooling into a frontend for open models, which lowers the cost of experimenting with local coding workflows.

• –The setup is minimal: point `ANTHROPIC_BASE_URL` at `http://localhost:11434`, use `ollama` as the token, and Claude Code can target Ollama-served models.
• –Ollama is framing itself as more than a local model runner; its homepage now treats launching apps like Claude Code, Codex, and OpenClaw as a first-class workflow.
• –The blog explicitly recommends coding-oriented models like `gpt-oss:20b` and `qwen3-coder`, showing this is aimed at agentic dev use cases, not just chat.
• –Anthropic SDK compatibility matters beyond Claude Code because existing Python and JavaScript apps can swap providers with a base URL change instead of a full integration rewrite.
