The info banner sat inside the genesis() function body, so it fired once per `wb genesis <op>` dispatch

Era was previously inferred from .era inside profile.json. Promote it to a first-class workbench-level input.

cardano-profile recognises the pparamsEpoch values that target PV 11 and adds a dijkstra zero stub and a v11-preview overlay so profiles can opt in.

Remove the "genesis spec" workbench command that was used for `create-testnet-data --spec-*` and instead use what cardano-profile provides.

The profile may have null "conway" or "dijkstra" genesis fields, but the node still needs valid files. Use a "zero" genesis in those cases.

Based on a mainnet db-sync and mainnet genesis files, reconstruct the timeline without baking in cardano-profile-specific assumptions.

Going forward, the only way to inject cost models with any number of parameters is through Alonzo genesis "extraConfig" field.

- Structure: cost models are separated from the rest of the parameters.
- Consistency: Shelley genesis is the full object, not only the "protocolParams" field.
- Consistency: cost models are an object everywhere, no arrays.
- Cost model names are updated.

These cost models were removed when the node started accepting only what mainnet shipped with.

The "ripper" backend assembles a run's genesis by combining:
- a cached **dataset**: UTXO, delegators, DReps, pool/staking keys
- a cached **protocol**: everything else

The existing "jq" backend stays as the default
