[FEATURE] Add testing for FUSE file operations

[sondavidb]

Description

In #1482, we fixed a bug where an update in go-fuse broke specific syscalls for seeking a directory. Most workflows seemed unaffected, but specific use cases would not be able to find specific files, even if they were present on disk.

We should add unit/integration testing to make sure that our FUSE file operations behave as expected, and possibly add some logs, as the failed FUSE operations were not able to be caught, even with trace logs.

Describe the solution you'd like

Unit/integration tests to ensure FUSE syscalls work as expected, and double-checking our FUSE logging to make sure we catch errors.

Describe any alternative solutions/features you've considered

If testing is considered not feasible for whatever reason, the logs should be checked to ensure errors are outputted properly.
