The in-memory store opened "file::memory:?cache=shared", an anonymous
shared-cache URI that SQLite resolves to a single process-global
database. Every store built via New("", ...) therefore shared one set of
tables, so the metadata tests were safe only because they ran serially.

Give each in-memory store a unique database name
("file:dingo_memdb_<N>?mode=memory&cache=shared") so connections within a
store still share, but separate stores are isolated, and mark the
package's tests t.Parallel(). The file-based production path is unchanged.

Cuts the package from ~31s to ~11s (-parallel=8) and the -race run
(make test) from 512s to 257s, race-clean.

Add an icon field rendered by AppIcon on cards and ToolDetail on detail pages (with an onError + colored-initial fallback). Source 79 icons under static/img/tool-icons/; Cardano Peer Connect intentionally has none and falls back cleanly. validation allows the icon key; showcase passes it through.

Reverses the earlier drop: Hydra ships hydra-node (a node you run to host an L2 head), so it belongs under Nodes & Network alongside Dingo and gOuroboros rather than being excluded as "just a protocol".

Dolos is TxPipe a lightweight Cardano "data node" (a third role beyond block producer and relay): follows the chain via Ouroboros and serves ledger data over Blockfrost-compatible REST, gRPC (UTxORPC), and Ouroboros node-to-client. Rust. -> Nodes & Network.

Add runAcquiredEbTxsSubscriber, the single writer of pendingTriggers. It
subscribes to the LeiosDb EB-notification channel and drains it forever. For
each AcquiredEbTxs notification (an EB whose closure has just become local) it
calls unblockCertRbsForClosure; an AcquiredEb is the body alone, the closure is
not yet complete, so it is ignored. Reading the notification and updating the
bookkeeping happen in one STM transaction, so no reader sees a CertRB that is
neither held back nor queued.

unblockCertRbsForClosure removes from announcementsMap every CertRB waiting on
the arrived EB and enqueues one reselection per removed CertRB onto
pendingTriggers. getBlockedCertRBs already stops holding these CertRBs back, so
the removal only keeps the map bounded; the enqueue drives the reselection.
Because removal and enqueue commit together, a re-arriving notification for the
same EB finds the entries gone and enqueues nothing, so each CertRB is enqueued
exactly once. A removed CertRB whose cache entry gcPruner already dropped is
skipped: the VolatileDB no longer holds that block, so reconsidering it is a
no-op.

This changes no behaviour: nothing forks the subscriber yet, so it does not run.
The ouroboros-consensus library builds under -Werror.

The node-snapshot (tvar) import path derived the current era's epoch size
from the network default (86400), ignoring custom-testnet genesis. Load the
history.<slot>.<hash>.json sidecar (as the .cbor path already does via
make_era_history) and use it to interpret the snapshot, but only for
Testnet(_); public networks keep the snapshot-derived history unchanged.
