v2.1.319

Claude Code v2.1.319 changes auto mode so calls the server can't check are asked about or denied when telemetry or feature flags are off, adds MCP task backgrounding in the terminal with a CLAUDE_CODE_DISABLE_MCP_TASK_BACKGROUND opt-out, and introduces a permissions.denyInsteadOfPrompting setting. It also adds /claude-api latency-optimize, spend breakdowns in /usage, several Claude apps gateway admin settings, and a long list of fixes spanning MCP, /diff, permissions, sandboxing, self-hosted runners, VSCode and cloud sessions.
