fix(acp): add claude-login auth method for ACP 0.20.0 compatibility

simonrosenberg · claude · simonrosenberg · commit cab3618037cb · 2026-03-03T20:42:10.000-03:00
The ACP agent was failing with "Authentication required" errors when
using claude-agent-acp v0.20.0 because the `claude-login` auth method
was not mapped to any environment variable.

This adds `claude-login` → `ANTHROPIC_API_KEY` to the auth method map,
allowing the SDK to properly authenticate with the Claude Code ACP
server when ANTHROPIC_API_KEY is available.
