After these changes, with DepFS we are using its multi-threading sharding technique to cache file `stat`s and the source file directive scanning results. We could use multi-threading sharding only to cache source file directive scanning results, and get rid of `DepFS` altogether, but then I don't see a good way to cache the file `stat`s as well, unless we want to try to re-use the `FileManager` across depscan instances and make its `stat` caching as efficient as DepFS (maybe by generalizing the multi-threading sharding technique and using it in `FileManager`). There's also `FileSystemStatCache` which seems like a leftover right now, but we could enhance it and have it shared by individual `FileManager` instances (instead of sharing the same `FileManager` in depscan instances). What do you think?
