Argus fails on serde example

[willcrichton]

To reproduce:

# Cargo.toml
[package]
name = "example"
version = "0.1.0"
edition = "2024"

[dependencies]
index_vec = { version = "0.1.4", features = ["serde"] }
serde = { version = "1.0.219", features = ["derive", "rc"] }

// src/lib.rs
use std::{collections::HashMap, hash::Hash, sync::Arc};

use index_vec::{Idx, IndexVec, define_index_type};
use serde::Deserialize;

trait Indexed: Clone + PartialEq + Eq + Hash {
  type Index: Idx;
}

#[derive(Clone, PartialEq, Eq, Hash, Deserialize)]
struct Local;

define_index_type! {
  struct LocalIdx = u32;
}

impl Indexed for Local {
  type Index = LocalIdx;
}

#[derive(Deserialize)]
struct Domain<T: Indexed>(
  IndexVec<T::Index, T>, 
  #[serde(skip)] HashMap<T, T::Index>
);

#[derive(Deserialize)]
pub struct Foo {
  pub bar: Arc<Domain<Local>>,
}

Click <..>::visit_map then Deserialize then Arc<Domain<Local>>: Deserialize. Get the error:
