Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

If you're willing to go REAL slow, there's still FPGAs. Something like this perhaps. Adoption would be pretty damned limited though, so your point stands.

What is a list of all softcores that were designed purely using VHDL?
I used this one https://github.com/lxp32/lxp32-cpu as base for building a RISC-V softcore.

RISC-V Assembly projects
https://github.com/enthusi/mandelbrot_riscv_assembler I have also some other examples, like a lz4 decoder.

What is a cheap (~$10) Risc-v that's simple to get started with?
Big thumbs up for the longan nano. Very cheap, super accessible and many many examples out there. From visual code via Makefiles to bare metal and with the LCD (and even SD card reader) you are not Limited to blinking LEDs. RV32, though. https://github.com/enthusi/mandelbrot_riscv_assembler

Beginner looking for basic assembly projects
Here is another full assembly example for the longan nano. Including LCD control, GPIO reconfiguration and input as well Mandelbrot math :) https://github.com/enthusi/mandelbrot_riscv_assembler
