Claude Code 2.1.280 makes Opus 5.5 default and tightens agent safety loops

Claude Code 2.1.280 adds Opus 5.5 and makes Opus the default on Pro and Team Standard plans. The release also fixes symlinked writes being approved under the wrong path, stops or backs off repeated auto-mode safety denials, preserves background subagent messages and reports, and adds a configurable MCP-description limit.
