Claude Code now reads AGENTS.md if there is no Claude.md

Claude Code, version 2.1.278, now defaults to a server-side classifier for auto mode on Claude API, Enterprise, Bedrock, Vertex, Foundry, and gateways, which eliminates classifier overhead charges. Users can opt out on Bedrock, Vertex, Foundry, and gateways using CLAUDE_CODE_AUTO_MODE_SERVER=0. Additionally, a fix was implemented for sandbox.excludedCommands, requiring all parts of a compound Bash command to match for exemption.
