Hobby Linux 0.8.0

tl;dr - Switch from Debian testing to stable and from kde to lxqt. Also alias apt with nala.

• Swap base distro from Debian Testing to Debian Stable (trixie)
• Switch from kde to lqxt
• Blacklist kde plasma so it doesn't get pulled in by deps
• Use Nala throughout install scripts
• Alias apt to nala for user session
• Remove flathub from install script
• Remove rspec tests
• Refactor linter to use fish instead of ruby
