Add Claude Code support with separate Docker image

[thepagent]

Summary

Add a separate Docker image for Anthropic Claude Code as an agent backend.

Approach

• Separate Dockerfile (Dockerfile.claude)
• Publish as ghcr.io/thepagent/agent-broker-claude
• Auth via ANTHROPIC_API_KEY env var

Helm usage

image:
  repository: ghcr.io/thepagent/agent-broker-claude
agent:
  command: claude
  args: ["--acp"]
env:
  ANTHROPIC_API_KEY: "${ANTHROPIC_API_KEY}"

Related: #14

Update: Use @zed-industries/claude-agent-acp adapter

Per OpenClaw's acpx registry, Claude Code uses the Zed-maintained ACP adapter (not claude --acp):

agent:
  command: npx
  args: ["-y", "@zed-industries/claude-agent-acp@0.21.0"]
env:
  ANTHROPIC_API_KEY: "${ANTHROPIC_API_KEY}"

Reference

• OpenClaw acpx built-in agent commands
• zed-industries/claude-agent-acp
