Add IntWidth enum with 8 variants and change Type::Int to Type::Int(IntWidth). Integer literals are now polymorphic — they get a fresh type variable constrained to integer types, with the concrete type determined by context and defaulting to i64. Cross-type arithmetic (e.g. i32 + i64) is a type error. Unsigned negation is rejected. Wasm codegen maps i64/u64 to ValType::I64 and all smaller types to ValType::I32 with appropriate truncation/sign-extension. Component ABI store functions are filled in for all widths. Overflow checking is generalized per type. Signed-off-by: rvcas <x@rvcas.dev>
