Caching tests: regenerate leaves-reads.msgpack from the C# reference (11 leaves x 28 tokens, 308 rows) and the README: timestamp rows, any rewrite binds value

 - `leaves-reads.msgpack`: an array of `[leaf, payload, accepted, rewrite]` for the wider leaves. `payload` (bin) is the

+  `d7ff0000000000000000`, `c70cff000000000000000000000000`, which the `any` leaf reads and rewrites as `91d6ff00000000`),

+  Every other leaf's rewrite binds bytes.
 - `leaf-record.msgpack`: `[members, payload]` for one `cultcache.leaf-record` document holding every leaf. `members` are
   the catalog rows the single-file store writes, each `[slot, memberName, typeName, isReference, isMany,
   targetSchemaName, isName, indexAlias]`; `payload` (bin) is the record's bytes in that store.
