fix: kernel projection panic in Sym.simp match reduction (#13635) 
This PR fixes a `Sym.simp` panic ("unexpected kernel projection term
during simplification") that triggered when matcher iota-reduction
exposed kernel `Expr.proj` terms via struct-eta. For example, a `do`
block with a `for` loop whose state is a tuple, where `Sym.simp`
unfolds the equational lemma and then descends into a destructuring
match.
