- Add clean and clean-all targets for artifact and venv cleanup
- Add install-doc target for documentation dependencies
- Improve documentation build process
- Add self-documenting help target with usage info
- Use consistent variable names and comments

The compile-time `crash-on-missing-key` cabal flag is replaced by a
runtime `--on-missing-key <crash|bottom>` CLI option (default: `bottom`).
`next` now runs in `Reader OnMissingKey` and the value is threaded through
`satisfies`/`satisfiesS` to all call sites.

`makeSizedTextStrings` and `makeSizedUtf8ByteStrings` had the same bug as
`makeSizedByteStrings`: they fmap'd a single seed across all sizes,
producing correlated string and decodeUtf8 benchmark inputs.

Extract the seed stream into a named top-level binding `splitSeeds` and
reuse it across all three sized-list helpers.

  Introduce HydraNodeConfig record type and smart constructors
  (mkSoloConfig, mkTwoPartyConfigs, mkThreePartyConfigs) to replace
  positional arguments in withHydraNode, withHydraNodeCatchingUp, and
  withUnsyncedHydraNode. Update all call sites in Scenarios, EndToEndSpec,
  ChainObserverSpec, TUISpec, and Bench/EndToEnd accordingly.

cardano-testnet | Fix flaky height check in rpc test

Tweag Disburse #2 2026

Replace the old fire-and-forget connection model with a supervisor in
`run_all` that owns the full lifecycle: initial registration (with
retry), per-connection tasks that reconnect independently on failure,
and periodic re-registration (every 30 min) that diffs the gateway list,
spawning tasks for new gateways and aborting tasks for removed ones.

Remove `run_once()` and the `platform_icebreakers` integration
test (fully covered by `e2e_websocket` tests after
243271b53a5c3d4f74502594f075918cbcdd118c).

So everything is in-line with previous naming which was
`test-something`, not `something-tests`.

We constrain both, the forged EBs and error out on the fetch client if
an EB bigger than the (hard-coded) limit is seen.
