This PR adds high priority to instances for `OfSemiring.Q` in the grind ring envelope. When Mathlib is imported, instance synthesis for types like `OfSemiring.Q Nat` becomes very expensive because the solver explores many irrelevant paths before finding the correct instances. By marking these instances as high priority and adding shortcut instances for basic operations (`Add`, `Sub`, `Mul`, `Neg`, `OfNat`, `NatCast`, `IntCast`, `HPow`), instance synthesis resolves quickly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Kim Morrison <kim@tqft.net>
