Cardano Updates

  Three cleanups spotted while reviewing the newLocalUTxO removal:

  - waitApplyTx and waitOnApplicableDecommit no longer pass the validated
    UTxO to their continuations (the callers stopped using it after the
    newLocalUTxO removal). Validation still happens; only the unused
    continuation arg is dropped.

  - pruneTransactions: rewrite from foldl' with `txs <> [tx]` (O(n^2))
    to guarded recursion with `tx : go u' rest` (O(n)). Threading the
    running UTxO through `go` is still required for validity checks
    on dependent txs.

  - TransactionReceived aggregate: replace `allTxs <> fromList [(k,v)]`
    with `Map.insert k v allTxs`. Same big-O class but eliminates the
    intermediate singleton-Map allocation per ReqTx.

  No behavioural change. Constant-factor wins on the per-ReqTx hot path.

Nixpkgs expects to drop support for intel macs in 26.11.

cardano-node 11.0.0's cabal.project pins index-state
'cardano-haskell-packages 2026-05-02T16:21:41Z'.  Our previous CHaP
input was at 2026-04-15T11:20:53Z, causing plan-to-nix to fail with
[Cabal-7159] during evaluation.  Bump to the latest CHaP commit.

drop support for x86_64-darwin

Pulls in master's current shared-image versions:
- sidecar:1ff6913       (post legacy-probe delete, #119)
- tracer-sidecar:5271661 (fork-tree probe build)
- configurator + log-tailer + tracer + cardano-node digests already match
- tx-generator from master is intentionally not added — adversary
  testnet runs nodes only

The adversary container itself stays pinned to its own SHA
(adversary:b75cfe3) since master has no adversary equivalent.

Layer 3 of #123 (perturbation metric emit from finally_tips_agree.sh)
is dropped: that script was deleted on main by #119, the cluster-wide
"did the cluster fork" oracle now lives in tracer-sidecar's fork-tree
probe. Re-implementing the perturbation metric on top of that surface
is a follow-up.

Adds Adversary.SDK with Reachable / Sometimes assertion emitters that
write to \$ANTITHESIS_OUTPUT_DIR/sdk.jsonl (default /tmp/sdk.jsonl).
Wires two assertions into app/Main.hs:

  - reachable("adversary_chain_sync_started", {target_host, point, limit})
    fires once per invocation before connectToNode. Antithesis report
    will show, segmented by target_host, "the adversary fired against
    pN at least once". A host that never gets attacked is visible as
    a missing Reachable hit.

  - sometimes(true|false, "adversary_chain_sync_completed",
              {target_host, tip|reason})
    fires once per invocation on completion. true on clean exit,
    false on connect/protocol failure. Sometimes-true vs Sometimes-
    false buckets quantify how often the adversary actually completed
    a full --limit sync vs being cut short by chaos.

Layer 1 of three for issue #123.

  newLocalUTxO was carried on TransactionAppliedToLocalUTxO,
  SnapshotRequested, and DecommitRecorded but is fully derivable from the
  event's tx (or snapshot fields) plus current state. Aggregate now
  recomputes it via a new IsTx method `applyTxTo` (pure UTxO arithmetic,
  no ledger validation).

  Removes O(N²) on-disk growth on Growing-UTxO workloads. JSON format is
  forward/backward compatible — old event stores still parse.

  Measured (bench-e2e --utxo-size Growing -n 2000):
  - hydra.db:         1.6 GB → 526 MB  (-67%)
  - hydra-node-0.log: 2.1 GB → 1.1 GB  (-48%)
  - avg confirm:      92.9 ms → 84.1 ms (-9%)

The endpoint is now deprecated, see also
* https://github.com/blockfrost/openapi/pull/451
* https://github.com/blockfrost/blockfrost-backend-ryo/pull/325

10.7.1 was released 2026-04-15 as the latest stable, supplanting 10.6.4.
11.0.0 (commit 1f5588d9, 2026-05-03) is tagged but its GitHub release
is still draft; pin to the tag for early CI exposure to the next major.

Notes for downstream:
  - 10.7.1 needs a chain replay (TablesCodecVersion1 changes on-disk
    encoding); LSM Tree backend replaces LMDB on OnDisk.
  - cardano-api: submitTxToNodeLocal now returns TxSubmitResult.
  - The new linux build deps (liburing/snappy-c/protobuf) are already
    handled by the prior overlay fix.

Archives unpacker that can know when a uncompression finished by locking
at the bytes, finishing immediatly.
In that case a race condition can occurs if the sender thread, that
reads the bytes from the remote location, do a last loop who will read 0
bytes, then `sender.send_async(..)` returns an "sending on a closed
channel" error.
