Overview

Cache producer that materialises the full ‘Hash<String, RBS::Definition>` for instance-side class definitions in the RBS environment, in a single cache entry. Mirrors the RbsConstantTable layout.

ADR-7 § “Slice 6-D” carry-over and dogfooding feedback: the earlier per-class cache layout (one entry per class, ~1300 files) made warm runs slower than ‘–no-cache` because each `instance_definition` call paid disk-open + `Marshal.load` overhead and the in-memory `RBS::DefinitionBuilder.build_instance` was actually fast given a cached `RBS::Environment`. The single-blob layout collapses that to one `Marshal.load` per process; warm runs now match `–no-cache` timing while preserving the cross-process invalidation story.

Marshal-cleanness of ‘RBS::Definition` is enabled by the v0.0.9 C2 `RBS::Location` patch.
