Cardano Updates

Scripts for running CIP experiments with deterministic turbo mode:
- run-deterministic.sh: per-experiment runner with voting mode, seed,
  and engine selection (turbo default, actor/sequential optional)
- run-all-NA.sh: runs all CIP throughputs (0.150-0.350) for a given mode
- run-all-voting-modes.sh: runs all throughputs x all voting modes
- combine-results-multi-vote.sh: collects results for a given voting mode
  into the format expected by analysis.ipynb

Add sim-rs persistent/non-persistent vote config fields to
experiments/config.yaml alongside existing Haskell sim fields. Both
halves are set to the same original CIP values so the weighted average
is unchanged. Without these, sim-rs silently uses defaults from
config.default.yaml (total probability 500 instead of 600).

The prune_old_leios_state function could prune an EB from node state
before an endorsing RB arrived, causing the node to add the EB to
incomplete_onchain_ebs with no way to validate it (body already gone).
This permanently set produce_empty_block=true, shutting down all block
production on affected nodes and cascading across the network.

Fix: don't add an EB to incomplete_onchain_ebs if it's in pruned_ebs
(meaning it was already validated before being pruned — no conflict
risk). Also add defensive guards in the pruning loop to skip EBs that
are in incomplete_onchain_ebs, and preserve ebs_by_rb mappings for
incomplete EBs.

Bisected: pre-pruning commit a1649012d produces 100% TX finalization
at 0.200 throughput; post-pruning ce028db2d collapses to 46%.

The worst-case numbers were unrealistic (plutus block limits prevent all
txs to have full plutus tx limits)

Add confirmed tx throughput to proto-devnet dashboard

Picks up the merged cumulative-tx-size work in ouroboros-consensus and
cardano-node now that both branches incorporate it on leios-prototype.

jemalloc handles concurrent allocation from rayon worker threads
better than glibc's ptmalloc2 (per-thread caches, less lock
contention) and returns freed pages more aggressively, reducing
RSS bloat from allocator fragmentation.

The deterministic event sorting pipeline (added in 54389c5ec) was
cloning and buffering every simulation event even when no -o output
file was given.  At T=0.250 with 1500 nodes this accumulated 7M+
OutputEvent structs (~10 GB) at peak, causing RSS to balloon from
~21 GB (actual node state) to 59 GB and OOM.

Guard the clone/buffer/flush path with a has_output check.  RSS at
slot 656 dropped from 59 GB to 28 GB — matching tracked node state
plus normal allocator overhead.

Also adds EventMonitor and LivenessMonitor stats logging every 60
slots for ongoing memory diagnostics.

Expose per-shard connection queue statistics (total/active connections,
queued messages, queued bytes) via a shared NetworkStatsCollector.
Each shard's sequential engine updates its counters at slot boundaries;
the node's existing log_memory_stats reads the aggregate.

Output appears every 60 slots alongside Memory stats, covering all
shards.  Initial profiling showed zero queued messages in turbo mode
(zero-latency clusters bypass bandwidth queues), ruling out network
queues as the cause of the ~40 GB RSS vs ~20 GB tracked-state gap.

Replace the full symmetrization (which nearly doubled link count from
39k to 59k) with a targeted fixup: for each node not listed as
anyone's producer, add a single reciprocal link back from its first
producer.  This adds only 432 links (one per BP) vs ~20k before.

BPs were the only nodes needing fixup — they pick 2 relay producers
but no relay was picking them back, making them invisible to the
sim's consumer-edge BFS.  Relays cross-reference each other enough
to be naturally reachable.

Re-generated topology: 38,943 links (vs 59,268 symmetric, 38,511
original asymmetric).
