Kelsi 2c5710b910 fix(terrain): NaN guards + zero-length checks on river/road/ridge generators ...

Same defensive pattern as paintAlongPath. carveRiver, flattenRoad,
and createRidge all called glm::normalize on a possibly-zero
direction vector, then divided by lineLen later. NaN endpoints
short-circuited dist comparisons and applied the height delta
to every vertex on every chunk.
