Overview

Cache producer that materialises the entire ‘RBS::Environment` (the loader’s ‘build_env` result) and round-trips it through `Marshal` against the patched `RBS::Location` (see RbsEnvironmentMarshalPatch).

Cold runs pay the full ‘RBS::EnvironmentLoader#load + RBS::Environment.from_loader + resolve_type_names` cost once; warm runs (and a separate loader sharing the same Store) load the marshalled blob and skip the parse / resolve stages entirely. The `RbsConstantTable`, `RbsKnownClassNames`, `RbsClassAncestorTable`, and `RbsClassTypeParamNames` caches still live alongside this producer — their cached values are reached without re-touching env, but when an uncached lookup happens (`instance_method`, `singleton_method`, …) the env produced here is what answers it.

Cache descriptor shape is shared with every other cache producer that depends on the RBS environment — see Rigor::Cache::RbsDescriptor.build.
