This kind of thread is what the Min/Max 3.X subforum is for, to be honest. As for giving you recommendations, there's not a whole lot to work off of when you already selected Elf race Diviner Foresight Wizard. I probably wouldn't ban Necro if I were you but you can use an Opposition Research discovery to get it back at 100%. For feats I can point out that Nature Soul -> Animal Ally -> Boon Companion will give you a full AC on top of your regular Wizard spell selection, which you can then enhance with the animal companion's Share Spells feature to polymorph it into some monstrosity. Best part is being able to get new animal companions on 24 hour basis. If you had 13 charisma you could've used Exotic Heritage -> Eldritch Heritage (Sylvan) to gain access to the full animal companion list, but at a larger level penalty.
If you want a cheesy Wizard I'd sooner recommend going Spell Sage Wizard. Spell Sage Wizard is the best for caster level cheese, scribing scrolls, and going full-on necromancer by poaching Cleric list for Desecrate and earlier reanimation spells (which you then cast at a higher caster level for more and better undead). Summoning legions of undead is still horribly overpowered, unsurprisingly. Yuelral's Blessing discovery will also give you some free CL and DC boosting while letting you pay for all expensive spell components in gems.
As an Elf, I'd replace Weapon Familiarity with either Aquatic Mastery (+1 DC to water-descriptor spells) or Fey Thoughts (get Perception and UMD as class skills). Then use Clever Wordplay social trait or Pragmatic Activator magic trait to get UMD as an int-based skill, use Reactionary combat trait to get +2 to initiative, and use a Drawback like Anxious or Meticulous to get a third trait of Lessons of Chaldira religion trait (1/day, reroll failed save), Deathtouched race trait (+2 trait bonus vs mind-affecting saves), or Defensive Strategist religion trait (You are not flat-footed before you can act in combat, not even in surprise rounds). If you want to go item crafting the Hedge Wizard magic trait reduces costs by 5%.
