Subject: [PATCH] fix: Fix mistake in `StatePropertyMetadataConstraint` type

In the `next` export of `base-controller`, the type
`StatePropertyMetadataConstraint` mistakenly referenced the old metadata
property name `anonymous` rather than `includeInDebugSnapshot`. The type has
been updated to use the correct name.
