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.

where are the LVDSs in tang nano 9K board?
This is how I declared some TLVDS for this HDMI transmitter I made a while back, hope it helps for reference, let me know if something looks off to you.

I've been working on my own DVI TX implementation, just tried out an SRAM framebuffer and it works! 180x120, 64 color goodness
You can check out the project on Github here.

Learning HDMI (via DVI-D) output on Gowin-4/Tang Nano 4K
The HDMI output is a good start, looks like we both settled on the signed coordinates idea, but I settled with the PAL bars and a bouncy box, the image you generated looks a lot more impressive than my bars!

How do I set up a clock source on a GoWin FPGA?
I assume you encountered the IPs provided by Gowin for both DVI and video framebuffer, I saw an open source implementation of DVI which now supports the Nano 4k. Haven't tried it and I assume you want to make it from scratch, but it's nice to have just in case.
What are some alternatives?
