This implements area recovery using area-flow heuristic.
The CutRewriter framework is changed to compute required time of the network. Currently it's simply set to worst arrival time of the initial mapping, in future enhancement this should be passed from users through some attributes.
The reselection is based on area-flow mentioned in
3.3.1 Global view heuristicin https://people.eecs.berkeley.edu/~alanmi/publications/2007/iccad07_map.pdf, which scores cut based on approximation of the shared logic amount.Assisted-by: Codex: GPT 5.4
