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.

Terminal Graphics for the 21st Century
Far far better than caca.
The subset of usable characters (glyphs) roughly defines how accurate the picture can be represented: if all you have is - and _ and you want to represent an horizontal pipe, it'll be ugly.
Of course it's more complicated than that, but caca uses ascii, while chafa uses a larger unicode range.
The example is illustrated in picture on https://github.com/csdvrx/derasterize where the left is the original basicidea.c using only unicode halfblocks, and the right has more candidate of different shapes.
Derasterize lets you select the width of the range you want to use, to improve encoding time say for video - but ideally, you would be able to test that whatever font you are using contains the glyphs you want.

She's not only done work with sixels but she's the maintainer of the highest quality tool for rendering images as unicode blocks. https://github.com/csdvrx/derasterize

Alacritty with sixel
On the application side, there is as yet exactly one terminal multiplexer that can handle images inside multiple terminals, but someone (saitoha?) did make a dev branch of tmux that could do it. /u/csddvx has I think the most recent version of that ; and her derasterize can make sixel work with non-sixel terminals which is a really neat trick.

Rust Is Portable
I feel some of the OP points. I was working on a profiling agent lately, and one of the issues was running it on multiple platforms (just the four big ones linux/mac-x86/arm) on FFI (because it'll be run directly from python/ruby/etc...) and preferably having the thing just work without having to install or configure any dependencies.
Like OP I hit two walls: libunwind, and linking. For libunwind, I ended up downloading/compiling manually; and for linking there is auditwheel[1]. Although it is a Python tool, I did actually end up using for Ruby (by creating a "fake python package", and then copying the linked dependencies).
It was at that time that I learned about linking for dynamic libraries, patchelf and there is really no single/established tool to do this. I thought there should be something but most people seem to install the dependencies with any certain software. I also found, the hard way, that you still have to deal with gcc/c when working with Rust. It does isolate you from many stuff, but for many things there is no work around.
There is a performance hit to this strategy, however, since shared dynamic libraries will be used by all the running programs that need them; whereas my solution will run its own instance. It made me wonder if wasm will come up with something similar without affecting portability.
Finally, the project is open source and you can browse the code here: https://github.com/pyroscope-io/pyroscope-rs
