d 🔹 ee5daba061 fix: resolve systemd restart loop with --replace flag (#576) ...

When running under systemd, the gateway could enter restart loops in two
scenarios:

1. The previous gateway process hasn't fully exited when systemd starts
   a new one, causing 'Gateway already running (PID ...)' → exit 1 →
   restart → same error → infinite loop.

2. The interactive CLI exits immediately in non-TTY mode, and systemd
   keeps restarting it.

Changes:

- Add --replace flag to 'hermes gateway run' that gracefully kills any
  existing gateway instance (SIGTERM → wait 10s → SIGKILL) before
  starting, preventing the PID-lock deadlock.

- Update the generated systemd unit template to use --replace by default,
  add ExecStop for clean shutdown, set KillMode=mixed and
  TimeoutStopSec=15 for proper process management.

- Existing behavior (without --replace) is unchanged: still prints the
  error message and exits, now also mentioning the --replace option.

Fixes #576
