config: raise agent max_turns 350->700, add goals.max_turns 40

Run 13 hit the 350-iteration budget mid-vuln-research and was force-closed
before EXPLOITATION (PTT 1/4, 0% formalized). The baked profile config
inherits max_turns into the agent iteration cap. Doubling it plus a 40-turn
goal continuation budget lets exploitable challenges get reached.
