[FEATURE REQUEST] add -h / --help flag

[erdnuesse]

Hi, for everyone dipping into the hypr ecosystem, it would be a real good improvement, where we could see the available flags, and default location of the config file.

Instead now -h / --help or /? are just being discarded as if no flags are present, and that could look like an error, or just not help anyone who needs just a quick reference, maybe if no browser is available on a vt or similar.

I don't expect a huge manpage, or tldr iclusion (though I love the latter), just a 4-liner for the flags, and not the actual, cold running attempt of the binary when -h, --help is present.
