Claude Code 2.1.281 hardens scheduled agents, resumed sessions, and MCP setup

Claude Code 2.1.281 fixes scheduled tasks and loop wakeups that could repeat every second after delivery failure, cloud and SDK sessions that could fail every turn after certain history states, and several resume, stream, permission, sandbox, and background-agent edge cases. It also adds MCP URL-mode elicitation and stronger plugin validation for insecure or silently dropped MCP configuration.
