Surely this behaviour is just a case of ESS being "too clever", sourcing
*.R files in special way when it detects that a file belongs to a package
(loading dependencies automatically, etc.)?

The function ss() is defined inside of .ess.source(), which is defined here:

https://github.com/emacs-ess/ESS/blob/5c4ae91cefa5c56fd13b204a9a996825af836a67/etc/ESSR/R/.basic.R#L168

If you think that there is a bug, then you could report it there ...

When I run a script foo.R containing some trivial code in my home
directory, via Emacs/ESS, everything works as expected: R
starts, and a setwd() command to set the working directory is
run automatically before the code in the script is run.

But if I copy foo.R to some package/R directory strange
things happen. When I use Emacs/ESS to run the script
in its new location, R starts, and setwd() is called to set
the working directory, but then one or more libraries that the
package depends on are loaded, even though I am using no
libraries in foo.R.

Now consider foo.R that contains the following trivial code:
secsToRDateTime <- function(secs) {
   day2sec <- 60*60*24
   days <- secs/day2sec
}

When I try to run this from package/R I get...

Error in ss(file, echo = visibly, local = local, print.eval = output,  :
   /tmp/gpstime.R!CuSewT:2:0: unexpected end of input
1: secsToRDateTime <- function(secs) {
    ^

As I said, there are no problems when the script is run from my
home directory. This suggests that test scripts can no longer be
tested in a package's R directory?

Is this true?

Thanks,
Dominick
