fix(ontology): complete PR 18 research graph

Align PR #18 with the Slayer Research Ontology v0.1 without changing the
published speech records.

The update versions the filtering protocol by content digest and immutable
commit URI. A follow-up metadata commit adds the complete Object, Version,
Relation, Protocol, Run, Evidence, Claim and Actor graph, plus contract tests
for references, acyclicity, immutable payload URIs and artifact checksums.

The data Parquet and attribution sidecar are reproduced from the pinned source
and must retain their previously published SHA-256 digests.
