Why is process-control interface being added? As issue #8 shows, snappy-debug suggests this interface because there is a seccomp violation on a sched_setattr system call. Is this affecting the functionality?

Yes, it does affect the functionality. Please see the PR description has been updated to include an explanation.
The solution, which involves running the scmp_sys_resolver command to solve the Seccomp violation, appears to be less user-friendly compareing to simply adding the process-control plug.

The data you shared shows the same success rate (4/50 timeouts) with and without connecting the interfaces. The delays may be caused by external networking and computing factors; it appears that the tests have been done in batches without randomization.
I'm not sure what solution are you referring to, involving scmp_sys_resolver. The shared document uses that command to resolve the syscall name from its ID.

This PR will resolve #8. As the issue described, there is a seccomp violation on a sched_setattr system call, and snappy-debug suggests adding the process-control plug.
chip-tool toggle command success rates :
9/10 (1 Timeout)
8/10 (2 Timeout)
9/10(1 Delay)
9/10 (1 Timeout)
7/10 (3 Timeout)
10/10
10/10
9/10 (1 Timeout)
Note: Timeout is a fatal error; Delay is not a fatal error.
Overall, using a process-control plug provides chip-tool snap with slightly higher success rates when controlling a device.
