Ramsey Upper Bound Improved to 3.49135655^k with Lean Verification

Developer ctjlewis improved the exponential base of the diagonal Ramsey bound to R(k,k) ≤ 3.49135655^k, verified in Lean. He also shared practices for making machine proofs more readable, cutting modules to under 400 and presenting verification in paper order.
