(Mama) Implement utils to detect local lockfile

[fraxken]

The idea is to implement a new utility function that detects the presence of a lockfile in a given directory. This new util function should be implemented in the mama workspace.

List of lockfiles:

• package-lock.json for NPM
• yarn.lock for Yarn
• others (pnpm, bun)

Then return the path to the file and the type. If nothing is found (or not supported) then the function should return null.

Using synchronous FS API (such as fs.existSync) should be enough for V1.

what do you mean by file type, is it extension of that files.

do we have to check all kind of lock files.

By filetype I mean a const string to easily identify if we are dealing with npm, pnpm, yarn etc.

The more we detect the better, but to start npm, pnpm, yarn and bun is probably enough.
