Adds an endpoint listing the UTXOs that hold a given script as a
reference script (CIP-33). These outputs can be used as reference
inputs (CIP-31) to execute the script without including its bytes.
A script may be held by multiple UTXOs, potentially at different
addresses, so the endpoint is paginated.

Response shape mirrors /addresses/{address}/utxos, omitting the
deprecated tx_index field (consistent with tx_content_utxo).

Lists the UTXOs that hold a given script as a reference script (CIP-33),
so a script hash can be resolved directly to its deployment UTXOs for use
as reference inputs (CIP-31) — without knowing/enumerating the holding
address.

- paged route GET /scripts/:script_hash/utxos
- query uses consumed_by_tx_id IS NULL for spentness
- response mirrors /addresses/:address/utxos, minus the deprecated tx_index
- requires @blockfrost/openapi 0.1.90

PR #1016 made a pool whose snapshot lags the current epoch surface loudly at
RUPD instead of panicking. This adds the recovery/prevention half so the lag
can neither be introduced silently nor double-applied on restart.

Piece A — guard the silent-corruption hole. `MintedBlocksInc::apply` accumulates
the block count into the pool's `live` snapshot slot, which only holds this
epoch's blocks when the snapshot is aligned. A lagging pool would silently fold
later-epoch blocks into a mislabeled slot, corrupting the `blocks_minted` reward
input. `apply` now asserts the snapshot is aligned to the block's epoch before
accumulating, failing loud and identifying (naming pool + epochs) at the origin
— block processing — rather than as a downstream RUPD failure. This sits in the
infallible delta-apply layer alongside its existing invariant `expect`s, so it
is a descriptive panic, not a propagating error. The block epoch travels on a
transient `#[serde(skip)]` field on MintedBlocksInc; WAL-stored deltas are only
ever undone (never re-applied), so the default it decodes to off the WAL is
never read — the WAL format is unchanged.

Piece B — make ESTART finalize run exactly once. Per-shard resume already skips
committed shards via `start_shard` (each shard commits atomically and advances
`estart_progress.committed` in the same write), and EWRAP finalize short-
circuits via `is_complete()`. ESTART finalize had no such guard — it was safe
only because the cursor advances in the same atomic commit as `EpochTransition`.
`commit_finalize` now asserts every shard committed and the epoch has not
advanced, returning BrokenInvariant::EpochBoundaryIncomplete (enriched with
epoch/committed/total) otherwise, converting a would-be silent double-rotation
into a loud, identifying error. Resume diagnostics updated to describe the
now-enforced mechanism (dropped the two "TODO: implement true shard resume"
notes).

Out of scope (deferred): rebuilding an already-corrupted pool snapshot window
from the archive for nodes that persisted a lag before this fix — they keep
failing loud with PoolSnapshotLagging and require a re-bootstrap.

ai: add GHA hardening skill and devShell .claude symlink

Signed-off-by: Akhil Repala <[email protected]>

Adds `BTreeSet` for sorting and deduplication, includes helper to
retrieve all known discriminants excluding unstable values.

db-synthesizer read the obsolete TestEnableDevelopmentHardForkEras key,
which cardano-node renamed to ExperimentalHardForksEnabled. On a config
that uses the current key, the development-eras flag defaulted to False.
That capped the node's max protocol version at 11 while the same config
scheduled Dijkstra (protocol version 12) at epoch 0, so every block was
rejected as ObsoleteNode and db-synthesizer forged nothing.

Parse ExperimentalHardForksEnabled, keeping the old key as a deprecation
guard that fails on inconsistent use, matching cardano-node's POM.hs.
Rename the vendored field npcTestEnableDevelopmentHardForkEras to
npcExperimentalHardForksEnabled.

Fixes #2075
