How to make a QR code with Stable Diffusion
The funny thing is that no-one AFAICT has realized that the same content can be encoded in different-looking QR codes. Beside the obvious (different error-correction levels), the content itself can be changed while maintaining its semantic meaning (e.g. "https://example.com/foo", "HTTPS://EXAMPLE.COM/foo", or "HtTpS://eXaMpLe.CoM/foo" are all semantically identical) and even the QR encoding itself can be tweaked (e.g. by changing the version and mask, see the demo on https://www.nayuki.io/page/qr-code-generator-library). Each combination would yield a different-looking QR code that would encode the same meaning, and it could therefore allow the diffusion models even greater freedom.
I'm sure somebody will get to this soon.

I want to secure my btc for a long term hold, but I don't know if I feel comfortable with cold storage.
Make a hidden Veracrypt vault on cold computer. Inside the Veracrypt vault save Keepassxc vaults. Store your seeds inside the Keepassxc vaults. For a paper backup, encrypt your seeds using an offline AES256/512 text encryptor/decryptor. Encode the encrypted text using an offline qrcode generator. Print out the qrcode. Test recovery using a dummy wallet. Be sure you can scan and decrypt. Bonus: Laser etch the qrcodes on metal plates. Make a multi-factor recovery vault, in case you forget your passwords. Shimar's secret sharing scheme is a useful tool for making your recovery vault. Never store your seed unencrypted anywhere, ever. Never input your seed on an online computer, ever. Always protect your seeds with something you know (password), something you have (vaults and keyfiles). Do not upload your vault to the cloud. Keep backups in multiple locations. Necessary tools: Cold computer: Any old computer will do. Just physically disable network access.

Ever wondered how a QR code works?
I probably know this only because back in time I wrote a QR code generator in JavaScript [1] which was also one of such libraries reviewed by Nayuki [2], and as I haven't actually implemented a decoder my knowledge stops there. Sorry :-)

Barcode Detection API
I guess it helps to understand how to generate a QR code: https://www.nayuki.io/page/qr-code-generator-library (see also the references at the end)
Good luck. ;-)

Alternative for Home Inventory/Moving?
Yet, IMHO any spreadsheet software would do. What it misses is tracking but that can be done with going from an ID, e.g number or hash or UUID, to an object and that itself can be done with generating and reading a visual code, e.g QR code. There are numerous open-source tools to generate these e.g https://github.com/davidshimjs/qrcodejs to generate then https://github.com/yushulx/javascript-barcode-qr-code-scanner to read. As long as you are coherent I'm not sure what the problem would be. If you have multiple users ideally the spreadsheet would be available via e.g NextCloud and the hash at the end of the URL would bring you to the right item or set of items e.g sheet or line.

How to use included open source software in my own github
I used a nice javascript thing to generate qr-code. https://github.com/davidshimjs/qrcodejs At the moment it is downloaded as is and checked in with my code. It feels a bit unfair, since it's not mine to have checked in, but how would I do it?

Simple chrome extension
In the above piece of code, we create a url variable, and create and show the qrcode variable. (creating the QRCode is basically an exact copy from the documentation at davidshimjs on github with the exception that we changed the hard coded link to the url variable we set earlier.
