Summary

The repository currently uses git submodules for managing Foundry contract dependencies located at crates/shared/primitives/contracts/lib/. These submodules add complexity to the development workflow (requiring --recurse-submodules on clone, potential sync issues, etc.).

Current submodules:

• forge-std (v1.14.0) - https://github.com/foundry-rs/forge-std
• solmate - https://github.com/transmissions11/solmate
• openzeppelin-contracts (v4.8.0) - https://github.com/OpenZeppelin/openzeppelin-contracts

Proposal

Replace git submodules with forge soldeer, the native Foundry package manager. This would:

1. Simplify repository cloning (no --recurse-submodules needed)
2. Provide better dependency version management
3. Align with modern Foundry tooling practices
4. Reduce git complexity and potential submodule sync issues

Tasks

• Install and configure soldeer in the contracts directory
• Add dependencies via forge soldeer install
• Update foundry.toml with soldeer configuration
• Remove .gitmodules and submodule entries
• Update any CI workflows that reference submodules
• Update documentation/README if needed
