Ardenas Barehand:
The way I read it, Fit is useful for regaining fatigue from physical activity (running, fighting, etc.)...
True enough. Fit is meant to recover FP lost to non-supernatural, non-long term effects* and activities.
Fit will recover FP spent marching, fighting, Extra Effort, etc.
* Starvation, dehydration, lack of sleep, etc.

...while Recover Energy recovers fatigue spent on casting or maintaining spells.
Recover Energy simply speeds up recovery of FP
during a rest. Which means
all FP lost which is recoverable via rest (so everything but long-term FP).

They don't stack, they do the same thing for different kinds of fatigue.
That's... that's debatable. I've allowed them to stack in games I've run, after all, it's usually not that much extra FP being recovered.
And there is nothing that states they don't stack.
