Cardano Updates

Adds hand-rolled counterparts that operate directly on raw BuiltinData,
bypassing valueOf's newtype/Maybe wrappers and unionWith's These algebra.
Hand-rolled union additionally skips the zero-filter, exploiting the
ledger invariant that tx-output Values have strictly positive quantities.

18 new bundles across the existing shape matrix (S1, S3, S8, S100):
14 lookup + 4 union-then-lookup, paired with the existing builtin and
non-builtin bundles.

Compares the Value builtins (unsafeDataAsValue, lookupCoin, unionValue)
against PlutusLedgerApi.V1.Data.Value's valueOf/unionWith across four
shapes (S1, S3, S8, S100) at four hit positions for lookup, plus
union-then-lookup. 108 goldens under test-ledger-api/.

For IntersectMBO/plutus-private#2177.

The builtin availability check in `scriptCBORDecoder` was using
`Set DefaultFun` for O(log n) membership, with a TODO suggesting
`IntSet`. A `UArray DefaultFun Bool` is a better fit: since
`DefaultFun` derives `Ix`, lookup is a true O(1) unboxed array index
with no conversion at the lookup site.

The array is built once per call via `runSTUArray`, folding over the
`Set` through its `Foldable` instance (no intermediate list). The
array covers all ~100 `DefaultFun` constructors.

`makeSizedByteStrings` used the same `H.Seed` for every element, so each
generated ByteString was a prefix of the same deterministic byte sequence.
Use `unfoldr (Just . Seed.split)` to produce a stream of independent
SplitMix seeds instead, giving uncorrelated content across sizes.
