Default 09 WRX...rattle/squeak from tranny or suspension just aftering starting

I've been noticing when I pull out of the garage in the morning after the car has been sitting that as I start moving down the street (from a stop) something squeaks or rattles as I engage the clutch in 1st gear. I thought it was the slave cyl/clutch fork squeak that so many manual trannys suffer from, but if I stop and push the clutch in and let it out, it is fine. However, if I have it in gear and I'm starting from a stop, I hear some rattly squeak from the front end.

I've tried rattling everything when I changed the oil this weekend (sway bars, suspension, drip tray, exhaust). I don't know what it could be. The reason I think it could be suspension is due to chassis/suspension flex as you start moving from a stop. Given how little miles are on the car, it very well could just be some bracket or something minor breaking in and sensitive to body/chassis/suspension flex, but you know how it is when you have a new car, you question every last sound, smell and sight.

EDIT: I forgot to mention that it goes away after the car warms up.

you should always let your car warm up before you take it out, right? If you do that it sounds like your problems are solved

I creep in 2nd until I get out of my neighborhood. By then the coolant temp is usually in the 170/180s.

I didn't notice it this morning....usually I notice it at work when the car has been outside for a 8 hours and I backout of my spot, and as I go to start moving in 1st and obviously turn to start heading straight, that is when I hear it most frequently.

So I think it is clutch related. It only happens as the clutch is partially engaged during a start from stop (whether I'm heading straight or turning during the start so I don't think it is steering/suspension).

To reiterate, I'm 100% sure it is not the release fork pivot because if, while stopped, I push in and release the clutch, I hear nothing. It's only while it is in gear and I'm trying to get moving.

I tend to be conservative on the throttle when starting from a stop (probably why I can hear it in the first place because if I revved any higher, the engine would cover the sound up).

Could it be the clutch disk damper springs or maybe a pressure plate still breaking in and while it is still cool, it makes a noise? The car only has 1866 miles on it total.
