Shared by `run_simulation` (Tab 1) and `_sim_point` (Tab 2 sweep) so both
tabs always hand identical kwargs to `cycle_sim`. If either tab wants a
swept/override value, it merges `{key: value}` into the input dict BEFORE
calling this helper.
The array ordering here MUST match what `murphy_unified/engine_bridge.py`
and the underlying engines expect. See `tabs/simulation.py` (pre-refactor)
lines ~237-258 for the original packing.
