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.

Xz format considered inadequate for long-term archiving
ZPAQ is the name of the tool but ZPAQ is also the name of the container format that gets used. ZPAQ embeds the decompression algorithm in the archive. One could store zstd-compressed blocks in ZPAQ archives as soon as a zpaql decompressor exists (e.g., for brotli there is a slow one implemented in a python subset and compiled to zpaql https://github.com/pothos/zpaqlpy).
I don't know exactly whether other formats are better for seeking and streaming, but since the baseline is tar, ZPAQ (in the 2.0 spec) is already better as it supports deduplication and files can even be updated append-only, and the compression is not an afterthought wrapped around it but well integrated.

QOI – The Quite OK Image Format
I don't know about CUDA, however I've made an AVX2 based encoder a few months ago : https://github.com/phoboslab/qoi/pull/143
I intend to create an AVX2 based decoder but I had absolutely no time to work on side projects in the past three months.
You might also want to take a look at this streaming encoder if you want to encode large files with a tiny memory footprint : https://github.com/MKCG/php-qoi/blob/main/src/FFI/lib/qoi.c
