#265 / #272: systemd_user_available() now requires XDG_RUNTIME_DIR and a
live D-Bus socket before probing systemctl --user, preventing false-positives
in containers (K8s/containerd) where systemctl exists but D-Bus is absent.
#274: Remove 'export' from CLASH_FOR_LINUX_SHELL_LOADED guard in profile.sh
generation so the variable stays local to the sourcing shell and does not
leak into child shells (VSCode terminal, tmux pane, bash subshell), which
was causing alias.sh to be skipped and http_proxy not exported in children.
#270: Ensure compinit is loaded before bashcompinit in the generated zsh
completion script so that compdef is available when bashcompinit registers
completions, fixing 'command not found: compdef' on zsh setups that do not
call compinit themselves.
#271: Extend container_env_type() to detect cgroups v2 + containerd/K8s
environments where /proc/1/cgroup only contains '0::/' and neither
/.dockerenv nor legacy cgroup keywords are present. Detection now also
inspects PID 1 comm and overlay root filesystem as fallbacks.
#266: resolve_runtime_ports() accepts an optional config-file hint; when
MIXED_PORT is not explicitly set in the environment, the port is read from
the config file being normalized. normalize_runtime_config() passes its
target file, so a user's 'mixed-port: 7899' in their subscription YAML is
preserved instead of being silently overwritten with the default 7890.
