Native Arbitraries

[gcanti]

Before its removal, the materialized fast-check bridge fixture
schema-toArbitrary-materialized-fast-check.ts measured 79.00 KB minified and gzipped.

Representative five-round runtime measurements against equivalent hand-written fast-check 4.9.0 arbitraries are
shown below. Values are median latency on Node 24.12.0 and Apple M3; lower is better. Both implementations validate the
same output domains, although their generation distributions are not identical.
