checkKazufunction

Whether an answer solves a puzzle: O(cells), no search, nothing remembered between calls. A browser runs it to say "done"; a server runs it before it believes a solve, so a grid that is right is accepted and a grid that was merely posted is not. It refuses rather than repairs: a grid of the wrong size, a value out of range or a given moved is a "no" with its reason, never a best guess at what was meant.

The rules of each puzzle are restated here rather than shared with the solver on purpose: the solver is what MADE the puzzle, and a check that reads the solver's mind proves only that the solver agrees with itself.
