Compatibility issue in `OrdinaryDiffEqExt` and `DelayDiffEqExt`

Setting up a project with `AlgebraicDynamics` and `OrdinaryDiffEq` on Julia v1.12.2 fails at precompilation due to issues in `AlgebraicDynamicsOrdinaryDiffEqExt` and `AlgebraicDynamicsDelayDiffEqExt`.

**Environment:**
```
[5fd6ff03] AlgebraicDynamics v0.2.2
[1dea7af3] OrdinaryDiffEq v6.59.3
```

**Error:**
```
Failed to precompile OrdinaryDiffEq [1dea7af3-3e70-54e6-95c3-0bf5283fa5ed] to
".julia/compiled/v1.12/OrdinaryDiffEq/jl_sVFQPJ".
ERROR: LoadError: UndefVarError: `tmp` not defined in `OrdinaryDiffEq`
Suggestion: check for spelling errors or missing imports.
```

It works fine on both 1.10 and 1.11. I appreciate you looking into this.

I also wanted to say—the framework is conceptually very intriguing. Thank you for designing it.
