This PR adds `Sym.Simp.evalGround`, a simplification procedure for evaluating ground terms of builtin numeric types. It is designed for `Sym.simp`. Key design differences from `Meta.Simp` simprocs: - Pure value extraction: `getValue?` functions are `OptionT Id` rather than `MetaM`, avoiding `whnf` overhead since `Sym` maintains canonical forms - Specialized predicate lemmas: comparisons use pre-proved lemmas like `Int.lt_eq_true` applied with `rfl`, avoiding `Decidable` instance reconstruction at each call site - Type dispatch via `match_expr`: assumes standard instances, no synthesis Supported types: `Nat`, `Int`, `Rat`, `Fin n`, `BitVec n`, `UInt8/16/32/64`, `Int8/16/32/64`. Supported operations: arithmetic (`+`, `-`, `*`, `/`, `%`, `^`), bitwise (`&&&`, `|||`, `^^^`, `~~~`), shifts (`<<<`, `>>>`), comparisons (`<`, `≤`, `>`, `≥`, `=`, `≠`, `∣`), and boolean predicates (`==`, `!=`).
