This issue has essentially cleared up for me in the last 3 wks, and only 3 things have changed in that period:
1. I moved from Boston to SF, so there's been a significant ambient temp change.
2. I have focused on my clutch release, trying for clean releases, and a constant speed of release.
3. I had my oil and oil filter changed.
Further context: When I got the car off the transport, I still noticed the sound. 3 days later I got the oil change, and the noise very rarely occurs now.
I did have the dealer look into it when I got the oil change, and they said they couldn't replicate it.
My guess at this point is that it's a temperature thing, as I was focusing on clutch release before the move, and I can't figure a connection between the oil/filter change and what seems like a clutch sound...
