What's fixed?

Previously, zhtSlope ("Slope Lift") was incorrectly grouped with zhtAuto and zhtSpiral, causing it to trigger SpiralLift.

This resulted in unintended spiral lift moves (G17 + G2/G3 arcs) on printers like the Creality Hi, especially during retraction before perimeter→infill travel.

Changes:

Replace boolean logic with explicit switch-case
Map:
zhtAuto → SpiralLift
zhtSpiral → SpiralLift
zhtSlope → SlopeLift (correct behavior)
zhtNormal → NormalLift
Eliminates unintended spiral paths and restores correct
slope-lift behavior on all machines.
