Summary:
Disabling `atime` on Linux is quite common. (I don't have data to back this up,
but with my sample size of n=1, 100% fall into this bucket.) In that case,
the plugins will be cached indefinitely.
Using `ctime` on the directory doesn't really mean anything because it is
only affected by changes *to* the directory, not the files inside.
So, let's do this right and use the most recent change to any of the files
*inside* the directory instead.

Summary:
There are 3 sources where plugins can be loaded from:
* `src/plugins`
* `src/fb/plugins`
* any path specified in `~/.sonar/config.json`
Plugins found in the first two directories are bundled with the app when building.
