State machine (direction memory) + Hysteresis (Version A)

----------------------------------------------------------------------------
|

We use two thresholds:
|
||||
T_hold (smaller): below -> treat as neutral and HOLD state
|
||||
T_enter (larger): above -> allow direction change (set by sign)
|
||||
|
||||
Behavior:
|
||||
If |diff| <= T_hold : hold direction
|
||||
If |diff| >= T_enter: set direction by sign
|
||||
Else (between) : hold direction
|
||||
|
||||
Presets (implemented as multipliers of the calibrated VdiffThreshold):
|
||||
T_hold = 1.0 * VdiffThreshold
|
||||
T_enter = 2.0 * VdiffThreshold
|
||||
|
||||
Inputs derived from v1, v2:

diff = v1 - v2
