docs: Regenerate settings.rst for companion settings

The docs CI builds Sphinx, which regenerates settings.rst from the
Setting classes in config.py and fails if the working tree changes. The
new Companion Processes settings were missing from the committed file.
Regenerate it (also picks up a stale grp.getgrnam line).

+Companion Processes
+-------------------
+
+.. _companion-config-file:
+
+``companion_config_file``
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Command line:** ``--companion-config``
+
+**Default:** ``None``
+
+Dedicated Python file the manager reads for companion specs.
+
+Lets companions reload independently of the main Gunicorn config.
+Example: ``companion_config_file = "/home/frappe/bench/companion.conf.py"``.
+If unset, specs are read from the main Gunicorn config.
+
+.. _companion-workers:
+
+``companion_workers``
+~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``[]``
+
+List of companion process specs, each a dict.
+
+A spec requires ``name`` and ``target``; other keys override defaults.
+Example: ``[{"name": "scheduler", "target": "app:run_scheduler"}]``.
+
+.. _companion-control-socket:
+
+``companion_control_socket``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Command line:** ``--companion-control-socket``
+
+**Default:** ``None``
+
+Unix socket the manager listens on for control commands.
+
+Clients send ``status``/``start``/``stop``/``restart``/``reread`` as JSON.
+Example: ``companion_control_socket = "/run/gunicorn/companion.sock"``.
+
+.. _companion-control-socket-mode:
+
+``companion_control_socket_mode``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``384``
+
+Octal file mode set on the control socket after it is created.
+
+Default ``0o600`` lets only the owner connect.
+Example: ``companion_control_socket_mode = 0o660``.
+
+.. _companion-stop-signal:
+
+``companion_stop_signal``
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``'SIGTERM'``
+
+Signal sent first when stopping a companion.
+
+The companion should catch it to drain work before exiting.
+Example: ``companion_stop_signal = "SIGINT"``.
+
+.. _companion-stop-timeout:
+
+``companion_stop_timeout``
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``60``
+
+Seconds to wait after the stop signal before sending SIGKILL.
+
+Give slow-draining workers a larger value.
+Example: ``companion_stop_timeout = 300``.
+
+.. _companion-reload-timeout:
+
+``companion_reload_timeout``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``60``
+
+Seconds to wait for the old child to exit during restart/reread.
+
+Used instead of ``stop_timeout`` when replacing a companion.
+Example: ``companion_reload_timeout = 30``.
+
+.. _companion-stdout:
+
+``companion_stdout``
+~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``None``
+
+Where to send companion stdout: a file path or ``"inherit"``.
+
+Files are opened in append mode; ``None`` inherits the manager's stdout.
+Example: ``companion_stdout = "/var/log/frappe/rq.log"``.
+
+.. _companion-stderr:
+
+``companion_stderr``
+~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``None``
+
+Where to send companion stderr: a path, ``"stdout"``, or ``"inherit"``.
+
+Use ``"stdout"`` to merge stderr into the stdout target.
+Example: ``companion_stderr = "stdout"``.
+
+.. _companion-cwd:
+
+``companion_cwd``
+~~~~~~~~~~~~~~~~~
+
+**Default:** ``None``
+
+Directory the child changes into before running the target.
+
+Example: ``companion_cwd = "/home/frappe/frappe-bench"``.
+
+.. _companion-env:
+
+``companion_env``
+~~~~~~~~~~~~~~~~~
+
+**Default:** ``{}``
+
+Extra environment variables merged into the child environment.
+
+Example: ``companion_env = {"QUEUE": "default"}``.
+
+.. _companion-startsecs:
+
+``companion_startsecs``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``1``
+
+Seconds a freshly forked companion must survive to reach RUNNING.
+
+Exiting earlier counts as a failed start and triggers BACKOFF.
+Example: ``companion_startsecs = 5``.
+
+.. _companion-restart-delay:
+
+``companion_restart_delay``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``5``
+
+Fixed seconds to wait before restarting a crashed companion.
+
+No exponential backoff; the same delay is used every time.
+Example: ``companion_restart_delay = 10``.
+
+.. _companion-manager-shutdown-buffer:
+
+``companion_manager_shutdown_buffer``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``10``
+
+Extra seconds added to the slowest companion timeout for the manager.
+
+Gives the manager headroom to stop all children before Gunicorn kills it.
+Example: ``companion_manager_shutdown_buffer = 15``.
+
+.. _companion-manager-stop-timeout:
+
+``companion_manager_stop_timeout``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Default:** ``None``
+
+Seconds Gunicorn waits for the manager to stop during shutdown.
+
+By default it uses the slowest companion ``stop_timeout`` plus a buffer.
+Example: ``companion_manager_stop_timeout = 120``.

+
+``enable_adaptive_queueing``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Command line:** ``--enable-adaptive-queueing``
+
+**Default:** ``False``
+
+Enable adaptive multi-queue routing in the ``gthread`` worker.
+
+Can also be enabled by setting the ``GUNICORN_ENABLE_ADAPTIVE_QUEUEING``
+environment variable to ``true``.
+
+When enabled, the worker splits its :ref:`threads` roughly evenly into
+two lanes — a *fast* lane and a *slow* lane — and routes each request
+to one of them by predicting, from previously observed timings of the
+same route (method + path), whether it will exceed
+:ref:`slow-request-threshold`. Slow-predicted requests go to the slow
+lane so they can never starve the fast lane, even under a flood of
+slow requests.
+
+Requires :ref:`threads` to be at least 2.

+A route is learned as slow once it has been observed exceeding this
