Setup issues

[redstrate]

I noticed these while re-testing on Windows:

• ANSI color formatting is broken in Powershell, and should probably be disabled there(?) - EDIT: This should be fixed upstream, or someone can contribute that themselves :)
• Hosts file is unfortunately required for Astra to function too, so I need to modify the documentation for that.

As explored in the dev chat, for the Linux version the LD_LIBRARY_PATH is not set and this isn't clear in the instructions. It should be handled by kawari-run automatically.

A user found the hosts setup confusing, and we should probably spotlight that more that every user should be going through that process.
