"California and Texas are community property states, so that means half your income is hers."
Correct. Which means that she must report 50% of your community income on her California resident tax return.
Since you were a full-year non-resident of CA with no CA-source income (assuming your wife earned zero CA income), she can file her CA return as MFS even if you file your federal return as MFJ.
