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.

Would rewriting a JS library in WASM(Rust) provide sufficient obfuscation?
There are wasm2c and wasmdec that decompile to C. There is also rewasm, which decompiles WASM to Rust. But I don't know if they can reconstruct non-trivial logic, e.g. shapes of structures.

Capturing the WebGPU Ecosystem
I think you're missing a good amount of nuance here
minified JS can be turned into reasonable JS, yes, but you're probably not going to get TypeScript code back, so the same sort of challenge exists there.
Assembly -> high-level language is harder, but there are absolutely binary -> C decompilers that are very popular/used in the RE community to make changes to existing programs.
But that doesn't even matter, WASM is much higher level than assembly, it's a stack machine, there is no arbitrary control flow / labels / `goto`, there are pre-defined data types, etc. all of this means it's easier to convert WASM -> high-level language than it is with a generic x86/arm binary.
There are WASM decompilers[0][1] which can convert WASM binaries into C code and back.
In both cases (minified JS and WASM), you're not going to get out exactly what you put in, but WASM doesn't really change the situation very much given the widespread adoption of 'compile to JS' languages like TypeScript these days.

Alternative for an existing plugin
Have you considered just transpiling it to C? Assuming it's the pseudocode you're after, that should be enough by itself. You could also lift it and recompile to whatever your preferred architecture is.
