h3_explore_temperature was positive-only (flattens the softmax -- more
exploratory, pulled away from the prompt's own weighting). Same knob now
also takes negative values (widget min -0.9) to do the opposite: sharpen
attention so it commits harder to what the prompt already made confident,
instead of only ever being pulled away from it. Same code path (temperature
= 1 + strength, dividing Q before the dot product), sign decides direction.
Floored at 0.05 so an out-of-widget-range strength can't drive temperature
to zero or negative. Fixed a NaN gap the floor doesn't cover: `!= 0.0`
(needed so negative values install at all) is also true for NaN, and
max(1+nan, 0.05) is nan, not 0.05 -- excluded explicitly.
Editor UI widget (engine_settings.js) updated to match.
