Running just without arguments should list recipes

[twcrews]

TL;DR: I think running just in a given directory should list available recipes (the equivalent of just --list).

The current behavior of running the first defined recipe is a carryover from make. It's not at all obvious to me, however, that this is a good design. The precedent for running commands without arguments is to display some kind of information. This usually takes the form of printing a version number or a help message. It's usually the first thing a user does when they can't be bothered to read documentation.

Optionally, this behavior could be overridden in the justfile or in an environment variable somehow, for those who want to preserve the make-like behavior. But I see no reason other than convention (tradition, really) that it remains the default.

This is admittedly opinionated, but I would argue so is the current behavior.

This poll is missing an option "No, but this should be overridable".

I think this is debatable, and as one datapoint I use the current behavior and I rarely use --list. Also, this is backwards incompatible, so it could only be changed with an edition. I'm curious what other people think though.

I would welcome this change. It's the default behaviour of many modern CLI tools, and it's the first thing I hack into every new Justfile.
