- find_docker() now checks HERMES_DOCKER_BINARY env var first, then docker on PATH, then podman on PATH, then macOS known locations - Entrypoint respects HERMES_HOME env var (was hardcoded to /opt/data) - Entrypoint uses groupmod -o to tolerate non-unique GIDs (fixes macOS GID 20 conflict with Debian's dialout group) - Entrypoint makes chown best-effort so rootless Podman continues instead of failing with 'Operation not permitted' - 5 new tests covering env var override, podman fallback, precedence Based on work by alanjds (PR #3996) and malaiwah (PR #8115). Closes #4084.
