This is good enough for the prototype, while a cleaner design would distinguish Praos-only or Praos+Leios "can be leader evidence type".

Constrain crypton to make sure we use memory (still, instead of ram)
For early-bootstrap (test) networks that hard-fork into an era at epoch 0 or 1 (CardanoTriggerHardForkAtEpoch -- test-only; real networks use AtDefaultVersion), copy the genesis-seeded ssStakeMark into ssStakeSet/ssStakeGo so the stake distribution -- and hence the Leios committee, which reads nesPd -- is fully active from the first epochs instead of only after the ~2-epoch stake snapshot pipeline. hard fork at epoch 0 => go = set = mark; epoch 1 => set = mark; epoch >= 2 / mainnet => unchanged. Benefits the Leios ThreadNet tests and any genesis-keyed devnet: the committee is stake-active from epoch 0, so voting and EB certification run immediately.

* Not derive the BLS keys anymore, but instead take them from the cardano-node CLI * Add BLS keys to the `PraosCanBeLeader` * Use the BLS keys from the ledger `PoolDistr` IntersectMBO/cardano-ledger#5988 * Switch to a stake-based committee selection that supports key-less seats IntersectMBO/cardano-base#693 * Generate and use new BLS keys in the `ThreadNet` tests * Seed the `set` and `go` stake snapshots when hard-forking at epoch 0 or 1, also PR onto `main` in #2191
