fix(generator): fix 6 generation bugs

- Fix JumpDirector diagonal drift - axis-aligned vectors per border side
- Fix schematic end-block - only last block triggers completion, skip scoring
- Fix JumpOffsetGenerator - clamp random offset to validator limits
- Fix JumpCalculator retry height clamp to -2
- Fix JumpValidator duplication - Vector.canJump delegates to common impl
- Remove rotateAroundY (offset already aligned with heading)
