Init.Grind.CommRing.Poly

We considered using a single set of definitions parameterized by Option c or simply set c = 0 since n % 0 = n in Lean, but decided against it to avoid unnecessary kernel‑reduction overhead. Once we can specialize definitions before they reach the kernel, we can merge the two versions. Until then, the IsCharP definitions will carry the C suffix. We use them whenever we can infer the characteristic using type class instance synthesis.
