Can anyone offer a (simplified) explanation of what's happening inside a
frequency shifter
circuit?

A frequency shifter will add the carrier frequency to all the harmonics
of the sound you want to shift.
A pitch shifter on the other hand will multiply by the harmonic
frequencies, keeping the original sound's harmonic structure intact, ...

John is correct in his response. Just as clarification (if you are into
numbers):
If a 500Hz fundamental is shifted by 100Hz, the pitch shifter will
"move" the fundamental to 600Hz, the second harmonic (formally 1000Hz)
1200Hz, etc. retaining the relationship of the harmonic. The frequency
shifter would shift the fundamental to 600Hz and the second harmonic to
1100Hz, thereby changing the relationship of the harmonics to one
another. Hope I am not all wet on this, but this is my understanding.
