not sure what's going on in fiat_parsers, after JasonGross/coq-scripts#16 there are module not found errors (can also be seen in the log of a successful CI)

for neural_net_interp it seems we're doing a partial build with less deps so the files with missing deps are not compiled
I guess this is a problem of rocq makefile invoking rocq dep once for all files it knows about instead of invoking it only for the files we want to compile

vst problem seems to be that there are a bunch of unused files with incorrect (outdated?) Requires
eg https://github.com/PrincetonUniversity/VST/blob/cbee87efb4bee2b588f8321e16b4cb7664d5cf60/msl/extract.v#L1 should be Require VST.msl.tree_shares but since the file is unused compilation doesn't error.

Could be fixed by fixing those files (just the Requires), deleting those files, or restricting the coqdep call to actually used files at https://github.com/PrincetonUniversity/VST/blob/cbee87efb4bee2b588f8321e16b4cb7664d5cf60/Makefile#L914-L930

@andrew-appel opinions?
