[PATCH 0/3] Container detection and AGENTS.md documentation

This series adds container environment detection to rteval and includes
documentation for AI coding assistants.

Patches 1-2 add container detection functionality that warns users when
running rteval inside containers (Docker, Podman, LXC, systemd-nspawn,
Kubernetes). This is important because latency measurements in containerized
environments may not accurately reflect bare-metal real-time performance.

Patch 3 adds AGENTS.md, a comprehensive guide for AI coding assistants
working with the rteval codebase, documenting architecture, conventions,
and development workflows.
