… cursor leak

Finalization now runs as chunk-sized serial-queue items (prepare, archive,
delete, complete) so gossip-driven pool operations interleave instead of
waiting for an entire epoch's worth of mined txs. The archive copies raw
proof-stripped buffers instead of deserializing and re-serializing each tx.

Also fixes a latent deadlock in TxArchive: getHeadIndex/getTailIndex called
.next() once on entriesAsync and abandoned the generator. Inside a write
transaction the committed-state iterator is unbounded, so the abandoned
generator never sent CLOSE_CURSOR, permanently leaking one of the store's
cursor semaphore slots per call and deadlocking the store after 8 archive
transactions.

- deleteFinalizedTxs re-checks each tx is still mined at or before the
  cutoff before deleting, since other pool operations may interleave
  between the finalization plan being computed and the delete chunk.
- archiveTxBuffers skips txs already archived, so a retried or crashed
  finalization cannot append a duplicate FIFO index entry whose eviction
  would delete the stored value out from under the newer entry.
- handleFinalizedBlock chains concurrent finalizations so their chunked
  queue items never interleave with each other.

PR #25032 added a top-level import of
standard-contracts/artifacts-historical/HandshakeRegistry-5.0.1.json, but
the release image dockerignore only whitelists artifacts/, so every node
started from a v5-line release image crash-loops at ESM link time with
ERR_MODULE_NOT_FOUND. This broke all spartan network deploys from
v5-next since 2026-07-29.

…#25155)

Since #25032, `@aztec/standard-contracts` has a top-level import of
historical artifact JSONs from
`standard-contracts/artifacts-historical/`. The release image
dockerignore ignores everything and then whitelists specific paths, and
it only whitelisted `standard-contracts/artifacts/` — so the historical
artifacts never made it into the image.

- Every node built from a v5-next release image crash-loops on startup
at ESM link time with `ERR_MODULE_NOT_FOUND` for
`HandshakeRegistry-5.0.1.json`.
- This has broken all spartan deploys from this line since 2026-07-29.
- The fix is a single whitelist entry:
`!/yarn-project/standard-contracts/artifacts-historical/`.

Split out from #25148 so the deploy fix can land independently of that
PR's review. Once this merges, #25148 will be rebased and its duplicate
commit will drop out.
