So what was the point of boring us with the story of it dying?

A run capacitor?

PS. I just plugged it back in and tried it again, and it's totally
dead now. I know that the burnt odor I smelled is the same as the
smoke that poured out of the fan this morning.

If you could put the smoke back it I bet it would be as good as new!
Never let the smoke out of an electrical device, its what makes them work.

Most likely all the lubrication was gone from the shaft making it
really hard to turn. As long as you kept it on and hot it was able to
turn. If it can't turn at the speed that it's intended then the
windings get very hot.. The motors are protected by thermostatic and
current overload protectors, about 3/4" long. One of these breakers
triggered. It can give quite a pop. It's fairly harmless because the
only fuel source is the insulation on the wires. The shellac coating on
the windings was burning and that's where the smoke and smell emanated
from.

Hi,
Most consumer grade fans are not specified to run 24/7.
Commercial/industrial/military spec items are different.
You fan over worked and burned out I am afraid. At least partially.
Another case of you get what you pay for. Sspeeding up means short in
the wiring due to burned insulation.

What's wrong with that? I would have
done the same, of course, under
controlled environment, i.e. you can
pull the plug fast. But seriously, a
pop could have been a starting
capacitor, however, I wouldn't think too
many window fans would have them. A big
attic fan, yes, a window fan,
iffey. "Not speeding up" would probably
indicate a bearing is probably
dry.
