LeanFrontier: first theorem submissions land, verified through the kernel

LeanFrontier accepted its first batch of machine-generated theorem submissions: the Furstenberg topology on the integers, the tent map semiconjugate to the logistic map, Lucas numbers and their Fibonacci bridges, the Fibonacci Q-matrix, and a closed form for the Josephus problem’s survivor. Submitted modules are now replayed through the kernel before acceptance, and the whole corpus is rechecked whenever Mathlib is upgraded.
