Add Sud.derive_plant_params(), which combines pot_mass/pot_material/
grain_mass/water_mass into a single lumped (mass, specific heat) pair
using approximate specific-heat constants for water, grain, and (by a
small material lookup table) the pot itself. demo_sud.py now builds
its plant_params from this instead of hardcoded C/M values, keeping
L/Td as the only manually-tuned plant parameters.

Now that duration is correctly read as seconds, bump the sample
schedule's hold steps from the placeholder 30-40s to more realistic
200-400s.

sude/sud_0010.json moved from a list of combined ramp+hold+wait
"Rasten" with global stirrer constants to a flat "schedule" list of
explicit {"type": "heat"|"hold", ...} steps, each carrying its own
stirrer_speed/stirrer_time_on/stirrer_time_off and an optional
user_wait_for_continue (+ user_message).
- components/sud.py: Sud now tracks the current `step` instead of
`rast`; "heat" steps enter RAMPING (advanced externally via
temp_reached()), "hold" steps enter HOLDING and count down
`duration` minutes (0 if omitted). Either step type can pause in
WAIT_USER via user_wait_for_continue, surfaced through the new
user_message attribute.
- tasks/sud.py: SudTask only pushes theta_soll/heatrate_soll on
"heat" steps, converts each step's stirrer_time_on/off into a
duty_cycle/cycle_time on every step change (replacing the old
state-based RAMPING/HOLDING stirrer switching), and broadcasts
user_message changes. Stirring is now fully schedule-driven instead
of implicitly stopped on WAIT_USER/DONE (DONE still stops it, since
there's no step left to read settings from).
- scripts/demos/sud/demo_sud.py: mirrors the same step-driven wiring.
- README's Mash schedules section rewritten for the new schema.
