Field report: walking onto hilly-looking colliders (the new convex rock
hulls are ramps) raised the character's Y, and with gravity zero +
SnapToGround off nothing ever brought it back down - the character
floated and its shadow drifted away.
Fix inside CharacterProcessor.PhysicsUpdate: capture the pre-update Y
and restore it (plus zero RelativeVelocity.y) after the CC sequence -
the character update itself can never change the movement plane, while
spawn/teleport writes made outside the update stay honored.
Deterministic + idempotent (rollback-safe), identical on server +
predicted client.
Verified live: player shoved into a cover-hull sloped edge decollided
~1 u horizontally with Y bit-exact at 1.0000 (the case that previously
rode up the slope); 466/466 EditMode, console clean.
