Bug Description

Cannot upgrade from req_llm 1.2.0 to 1.3.0+ due to duplicate TypedStruct module conflict. The reversion to typed_struct in PR #315 causes production build failures for projects using typedstruct (the maintained fork) alongside req_llm.

Reproduction Code

# mix.exs
defp deps do
  [
    {:req_llm, "~> 1.3"},
    {:typedstruct, "~> 0.5", override: true},  # or via transitive deps
    # ... other deps
  ]
end

Then run:

MIX_ENV=prod mix release

Expected Behavior

Production release should build successfully with req_llm 1.3.0+.

Actual Behavior

Build fails with:

** (Mix) Duplicated modules: 
    'Elixir.TypedStruct.Plugin' specified in typed_struct and typedstruct
    'Elixir.TypedStruct' specified in typed_struct and typedstruct

Both typed_struct (from req_llm 1.3.0) and typedstruct (maintained fork, from other deps) export identical modules, causing the conflict.

Environment

• ReqLLM: 1.3.0
• Elixir: 1.19.5
• OTP: 28

Additional Context

Our project uses TypedStruct directly in application code. We have typedstruct in our dependency tree for compatibility with other packages. When req_llm 1.3.0 added typed_struct (via PR #315 to fix jido ecosystem conflicts), it introduced this duplicate module issue.

Currently pinned to req_llm 1.2.0 which uses typedstruct and doesn't conflict. I understand PR #315 was necessary for jido ecosystem compatibility, but it creates issues for standalone req_llm users. The Zoi migration would resolve this permanently.

Thanks @neilberkman - as discussed in chat, this reversion was needed for Jido. In Jido, TypedStruct is on it's way out - but it takes time.

I'll look into accelerating our move to zoi to help address this

Thanks @mikehostetler, I really appreciate it!
