A clover of same-size rectangles drawn around a shared corner was refused as over-constrained.
Constraints that remove no degree of freedom but still hold (zero residual) are now kept and shown dimmed as redundant. Conflicting ones are still refused. A redundant driving dimension is refused with "already determined by ...". Typed sizes become driven (reference) dimensions. Drawing no longer adds Horizontal/Vertical to a side that is already implied through two coincident corners. The solver reports redundant constraints using a Jacobian row-dependence test.

`sketch.constraint.symmetry` (line), `parallel`, `perpendicular`,
`collinear`, `tangent` and `coincident` (point on curve) now take `x` /
`y` for the sketch's own axes, matching what `solid.revolve` means by
lowercase x|y. A real curve with that id still wins.
An axis becomes a linked construction line on it: a new
`LinkSource::SketchAxis` resolved in sketch coordinates, so it stays on
the sketch's axis on any plane, is shared by every constraint on that
axis, is left out of profiles and is reported in `created`. Equal,
concentric, midpoint and horizontal/vertical keep refusing axes, since
the axis line's finite length or fixed direction would make them
meaningless.
