feat(character): 16.8 - on land a physics walker moves the body (CharacterGround.walk); the package's own gravity, ballistic air and slope-probe refusal are gone

Browse source 
The package keeps the rules and hands them over each step: speed and heading, whether a jump
leaves, CHAR_STEP and the boots' slope limit. The walker (Jolt CharacterVirtual) does gravity,
landing, steps, slopes and following the ground down. Too steep is ground too steep facing the way
the body wanted to go; stepping off an edge is not. ludic.physics: phys_walker_move (follow the body
if something else moved it, then step), the slope limit, the jump always honoured. The character's
tests run on a real Jolt walker over the same fake world: 15 pass, a knee-high boulder now a step.
