I'm saying Pin 9 (XTAL1/TOSC1) of the 328 is shorted to Pin 8 (GND). For an Arduino, this is bad.

Although not as bad - you should have a line connected from GND to the trace BETWEEN the two oscillator (probably 18pF-22pF) caps. But I've seen processors run without this.

I don't see a ground between these caps.

Here's the fix:

Oh, sorry, I thought that's what we said.

Now that it's working, if you want your reset-button/auto-reset function working, you'll need a jumper from Pin #1 of your ATMEGA to the "RST" (far left) pin of your Reset header (to the right of the "Programming" header).
