When stderr is connected to journald, switch from the plain text handler to the native journal protocol via github.com/systemd/slog-journal. Each record now carries PRIORITY, MESSAGE, and slog attributes as structured fields, so journalctl -p and LogLevelMax= in unit files filter by severity instead of dropping everything at once. Detection follows systemd.exec(5): parse JOURNAL_STREAM as <dev>:<ino> and fstat(2) stderr to confirm the match, guarding against processes that inherit the env var but have stderr redirected elsewhere. The fstat path is Linux-only; other platforms fall through to the existing text handler. Also honour DEBUG_INVOCATION by raising stderr to Debug level, matching the behaviour of systemd.service(5) RestartMode=debug.
