What is the behavior when there are multiple stage_fixed commands and parrallel: true is used?

Hey,

Before trying to experimentally determine this, I thought I'd ask - what is the behavior of lefthook when we have something like the following configuration that uses bot parallel: true and stage_fixed: true commands:

pre-commit:
  parallel: true
  commands:
    lint:
      glob: "*.{js,ts,cjs,mjs,d.cts,d.mts,jsx,tsx}" 
      run: pnpm eslint --fix {staged_files}
      stage_fixed: true
    prettier:
      glob: "*.{js,ts,cjs,mjs,d.cts,d.mts,jsx,tsx}" 
      run: pnpm prettier --fix {staged_files}
      stage_fixed: true

It is possible for the above configuration for both commands to change the same file, so I wanted to know what would lefthook do?

In this case these commands will be executed concurrently and the one that finished last will be the winner. In details, it depends on how eslint and prettier work with files: modify them or create a copy and then replace the original with the new version. I guess it's the second (the same text editors work with files). If I'm right, the last command finished will persist the file.

No matter what command finishes last files will be staged for both since they are being staged concurrently also.
