Add OpenSpindle to Controllers & Apps

[blackveilprecision]

What does this add or change?

Adds OpenSpindle to Controllers & Apps:

- [OpenSpindle](https://github.com/openspindle/openspindle) - Open-source desktop app for setting up, simulating and running Z1 jobs, with probing, Fusion 360 import and PCB prep; early alpha.

It's an MIT-licensed Windows and macOS app (currently v0.3.0) for preparing, checking and running jobs on the Makera Z1. The description says "early alpha" because the project's README labels it that way and lists features not yet verified on a real Z1.

Checklist

• Each entry looks like - [Name](https://link) - Description. and is in alphabetical order within its section.
• Descriptions are one sentence, start with a capital letter, and end with a period.
• Links go straight to the resource (no affiliate, marketplace or shortened links).
• I ran PYTHONPATH=.github/scripts python3 -m awesome_bot validate (0 errors), the unit tests, and awesome-lint locally.
• I'm affiliated with something I added (if so, say which).
