js-rigor: partial-graph overlay parity campaign
Pins the partial-graph contract: persistent-over-partial direct overlay,
layer-trust conflict precedence (token_projection > partial), registry-
gated per-relation reducers (strongest/weakest/first on listed relations;
unlisted relations reject the reducer with a first-kept fallback),
conflict_mode strict throws, reserved relations skipped, chain traversal
merging persistent+partial edges incl. partial-only temp nodes, and
read-only contexts (persistent state untouched).
