refactor: ✨ (#418)

* refactor: ✨ move in one commit Eveything in modules should probably be changed to `exported` defs. The idea is to move everything first to keep proper history. * refactor: 📝 add modules readme (wip) * refactor: ✨ small move * refactor: 📝 changed nestring, updated modules readme * refactor: 📝 to document or not to document * fix: 🐛 themes replaced the template to use `main` and regenerated them from lemnos themes. * Revert "fix: 🐛 themes" This reverts commit 4918d3633c8d2d81950a0ed0cfd9eb84241bc886. * refactor: ✨ introduce sourced - Created a source `root` in which sourcable demos are stored. Some might get converted to modules later on. - Moved some files to bin too. * fix: 🐛 fehbg.nu * fix: 🐛 modules/after.nu * moved some other stuff around --------- Co-authored-by: Darren Schroeder <343840+fdncred@users.noreply.github.com>
