It would be good to enable hardhat coverage in this template repo as a PoC.

I just went through the exercise on a project utilising this template and had to do the following to get hardhat coverage to work:

1. install and import @nomicfoundation/hardhat-toolbox in hardhat.config.ts
2. Install all the external libs/pkgs in ./lib using your project's node package manager(i.e. yarn, npm or pnpm) and ensure that these packages are now visible in the package.json and node_modules
3. before running hardhat coverage you'll first have to comment out the preprocess config in the HardhatUserConfig to disable it

Currently the .gitignore file of the project does not include the broadly used .env across the majority of projects.

Users might be unaware of this and push sensitive information potentially putting funds and access control at risk.

Add .env to the .gitignore on this and any other template you offer where it might be missing.

One of my forge installed libraries uses this import path for it's OZ dependency:

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

Another one of the contracts from a different library uses this import path:

import "openzeppelin-contracts/contracts/access/AccessControl.sol";

My OZ dependency lives in lib/openzeppelin-contracts

My remappings are as such:

@openzeppelin=lib/openzeppelin-contracts/
openzeppelin-contracts/=lib/openzeppelin-contracts/

Unfortunately, the hardhat preprocess does a sed which means that it does the following:

1. Replace @openzeppelin with lib/openzeppelin-contracts/
2. Replace lib/openzeppelin-contracts/ with lib/lib/openzeppelin-contracts/

I was able to resolve the issue by changing the order of my remappings to avoid the overlap, but this issue may affect others
