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

+# Nushell Password Generator "nupass"
+
+This nushell command randomly retrieves three words from a dictionary file (English with Japanese words added by @rickcogley) less than or equal to a given parameter's length, formats the words randomly with capitalization, then separates the words with some random symbols and numbers to return a password.  
+
+To use:
+
+1. Get the dictionary file to your system using nushell's `http`:
+
+```
+http get https://raw.githubusercontent.com/RickCogley/jpassgen/master/genpass-dict-jp.txt | save genpass-dict-jp
+```
+
+...which has also been included in this folder for convenience. 
+
+2. Confirm your `$env.NU_LIB_DIRS` location, and copy the below script `2. nupass.nu` there as `nupass.nu`.
+3. Set the script as executable like `chmod +x nupass.nu`
+4. Specify the dictionary file's location in the script: 
+
+```
+let dictfile = $"/path/to/my/genpass-dict-jp"
+```
+
+5. Confirm the symbols are what you want to use, and edit to taste: 
+
+```
+let symbolchars = "!@#$%^&*()_-+[]"
+```
+
+6. Load the script with `use` in your `config.nu`, something like: 
+
+```
+use nupass.nu
+```
+
+(you can specify the path as `use /path/to/nupass.nu` if you're not taking advantage of `$env.NU_LIB_DIRS`)
+
+Reload nu, then run it to test:
+
+```
+nupass -h
+nupass 5
+nupass 6 --debug
+nupass 3 -d
+```
+
+### Testing
+
+If you're making changes to the script while testing, just re-source the script by doing: 
+
+`use nupass.nu`
+
+... which will reload the latest save.
+
+### Caveats
+
+I've been scripting for quite a long time, but not in nu. Input appreciated to make this more nu-esque!
+
+Obviously you can just use the `random chars` or `random integers` commands but I like to have words I can read in my passwords, and I think those generated by this script have sufficient entropy. 
+
+This command doesn't let you specify a precise length. 
+
+### Acknowledgements
+
+Thanks everyone on Discord for putting up with and answering my nubie questions @amtoine, @fdncred, @jelle, and for the feedback after try number 1.
