Source files have Solidity version locked to 0.8.23, limiting extensibility

### Source files have Solidity version locked to 0.8.23, limiting extensibility

All contracts in the repository have the Solidity version strictly locked to `0.8.23`. While I understand the security motivations behind using an exact `pragma`, I wonder if a more flexible version (e.g., `^0.8.23`) could be considered — especially since this is a framework meant to be extended by downstream projects (e.g., `EIP7702DelegatorCore`).

Locking the version makes it difficult for projects using newer Solidity versions to inherit from or build on top of these contracts without compiler conflicts. Relaxing the version constraint would improve developer experience and encourage broader adoption.

Thanks

Start by locating the repository's Solidity source files and reviewing EIP7702DelegatorCore, the downstream extension named in the issue. Assess how a more flexible compiler constraint affects inheritance and builds with newer Solidity versions; done means the chosen constraint is applied consistently and compatibility is verified.
