Use 'canonical' PlutusData encoding in machine's runtime builtin
feat(blockfetch): parallel shadow blockfetch with per-peer latency tracking
Add four-phase parallel blockfetch improvements: Phase 1 - Per-peer blockfetch latency EWMA: Track first-block response latency per connection using exponential moving average (alpha=0.2). New methods: RecordBlockfetchLatency, BlockfetchLatency on chainsync state. Phase 2 - Latency tiebreaker in chain selection: When two peers have equal observed tips, prefer the peer with lower blockfetch latency before falling back to connection ID string comparison. Phase 3 - Shadow blockfetch dispatch: For small near-tip batches (<=4 headers), dispatch the same RequestRange to a second peer that has already seen the block header. Accept blocks from whichever peer responds first with hash-based dedup to prevent double-apply. Phase 4 - Node wiring: Connect PeersWithBlock, RecordBlockfetchLatency, and BlockfetchLatency callbacks through LedgerStateConfig and ChainSelectorConfig. Signed-off-by: wcatz <[email protected]>
Convert SIGTERM to SIGINT in N2C harness
GHC handles SIGINT (UserInterrupt) but not SIGTERM by default. The harness converts SIGTERM to SIGINT so Haskell services (ogmios, kupo) get a chance to clean up. Both still exit 130 — upstream issue, needs filing. See: https://github.com/IntersectMBO/cardano-node/issues/2267

Fix error "impossible!" in fetch decision logic
The three-layer lookup in goTx2 used `Map.lookupMax` on an EB-hash-keyed map to extract the tx's byte size. The picked offset may belong to an EB other than 'point', so using it as a key into 'point''s IntMap could either crash with `error "impossible!"` or silently yield the wrong tx's size. The tx's byte size is already in scope at target-construction time in `expand`. Capture it into the target tuple (`Right (point, txBytesSize, txHash)`) and thread it into goTx2 as an argument. The three-layer lookup and its FIXME are removed; both failure modes are eliminated. Addresses https://github.com/input-output-hk/ouroboros-leios/issues/862
