hardhat test solidity seems to hang because we don’t have a spinner or something during compilation.

We should also update in place the text: Nothing to compile, to avoid adding lots of extra lines.

• The spinner should appear when contracts and tests are compiling.

• The spinner should be at the beginning of a new line at the end of the CLI output and then be replaced by the result once compilation is done.

• Any errors or warnings push the spinner to a new line after the message

• The spinner implementation must not add a new dependency and must be in hardhat-utils to be available to other projects

• Original state

  root@5a079a243a54:~/hardhat_test# pnpm hardhat compile
  Compiling your Solidity contracts...
  

  That turns into the following when the compilation completes.

  root@5a079a243a54:~/hardhat_test# pnpm hardhat compile
  Compiling your Solidity contracts...
  Compiled 4 Solidity files with solc 0.8.28 (evm target: cancun)

• Spinner output

  the final message replaces the spinner once complete
