checkCallArity compares the supplied count against the declared params (min = params without trailing defaults, max = params.len, unbounded past a variadic) at the five plain dispatch sites in lowerCall — bare selected-author + lazy, namespace alias-gate + qualified, struct method, ufcs. Pack / comptime / generic / #compiler / #builtin callees keep their own dispatch. The method/ufcs sites also gain the appendDefaultArgs fill the generic-instance leg already had, so trailing defaults work on dot-calls instead of emitting under-arity calls. lowerStmt's local fn_decl arm now registers a pointer into the AST node in fn_ast_map, not a stack temporary that aliased every later local fn.
