Trevor BrownandClaude Opus 5.5 dc841f8548 M8: vector.edit.position moves points in one pass; refusal, empty-selection and scrub tests ...

The handler grouped equal offsets by a linear scan per point, quadratic when every point moves
by its own offset. Only a single move covering every point carries the regions' paint frames,
so it now checks in one pass whether all offsets are equal: if so the points move as one,
otherwise each moves by its own offset. The result is the same as before.

Tests: booleans, a valid x with a refused y, and the overflow case are refused with no undo
step; nothing selected is refused; a shared Y scrubs every point in one undo step and a Mixed
X doesn't scrub. selection_position's doc comment names its one user, vector.edit.bounds.
