A player in our group is looking to play a humanoid woman who can naturally change shape into a wolf as a part of her character concept; though she isn't infected with lycanthropy. Since she's supposedly been doing this since birth, is there any way for a character to effect that transformation at 1st level?

You're looking for the Skinwalker Race. It fits the bill perfectly.
The skinwalkers can't actually assume an animal form without a specific magical item though. And it is expensive enough that a level 1 character wouldn't start with it without GM help.

It isn't PFS being 3rd party, but you should have a look at the Okami variant of the Kitsune.
By default the Okami has a 'wolfman' and human form, but has a racial trait option to become a wolf. Normally this trait requires BAB+3 and WIS 13, but a chat with the GM should sort out the BAB prerequisite.
I have used this option for my character who I envisage as a wolf who takes human form rather than vice-versa.
