Both blocks were nearly identical (config.json.sim's differing M and
unused gain key being the only divergence), so there's no need for
per-config tuning here. DEFAULT_PLANT_PARAMS in brewpi.py now feeds
both the real Pot plant and the temperature controller's
Smith-predictor model. No demo scripts read these config keys, so
nothing else needed updating.

[Pot] - removed the gain (efficiency) factor and the separate
"theta" initial-temperature param; Pot now starts at theta_amb and
set_power()/get_power() operate on p_in directly. Added
set_ambient_temperature() for live ambient updates. Dropped the
now-unused "theta"/"gain" keys from Model/Plant in config.json.sim
and config.json.templ (also fixes a JSON syntax error in
config.json.templ: trailing commas left over after removing "gain"
made Model/Plant fail to parse).
[Sensor] - fix missing space in TempSensorSim.temperature()'s
offset/variance expression (cosmetic, no behavior change).

brewpi.py had a dead -m/--model CLI arg and sude/*.json schedules were
pure data with no code to drive them, despite the README documenting
them as if they were already wired up.
Add components/sud.py's Sud, which loads a sude/*.json schedule and
steps through its Rasten (ramp -> hold -> optional wait-for-user ->
next rest), and tasks/sud.py's SudTask, which drives the temperature
controller's theta_soll/heatrate_soll from the current rest and
switches the stirrer between continuous (ramping) and intermittent
(holding, via stirrSpeedRast/stirrDutyRast/stirrCycleTime) operation.
Exposes progress on a new "Sud" WebSocket channel and accepts
Start/Confirm commands. Enabled via a new optional top-level "sud"
config key (see config.json.templ/.sim).
"Reached target" is detected via abs(theta_ist - theta_soll_set) <
tolerance rather than tc.state == HOLD, since the latter can still
read HOLD left over from the previous rest for one tick after a new
target is pushed (tc.state only updates on the controller's own,
independently-scheduled process() tick).

brewpi.py passed a literal 20 as theta_amb to Pot, and
temp_controller_smith.py's two internal Pot models (and every demo's
Pot/TempController instantiation) silently relied on Pot's default of
20 instead. Add a top-level ambient_temperature key to
config.json(.templ/.sim), thread it through brewpi.py into both the
real plant and the Smith predictor's models via a new theta_amb param
on TempController, and make the demos pass it explicitly too.

- ws/message.py, ws/server/ws_server_multi_user.py: drop the loop= kwarg
and replace asyncio.wait(coroutines) with asyncio.gather(), both of
which were removed/forbidden in Python 3.10+.
- brewpi/requirements.txt: pin websockets==10.4, the latest version that
still supports this code's serve()/handler API.
- config.json.sim: move Model to the top level and add the missing gain
field so it matches the schema brewpi.py and config.json.templ expect.
- brewpi/brewpi.py: add -c/-m/-s/-d CLI args for selecting config/model
files, simulation mode, and debug.
- .gitignore: exclude __pycache__, logs, the local config.json, and
editor/venv directories.
