fix(SpacesExtractor): emit inline non-hasAdmin role RIs from gen:Space

[tkuhn]

Summary

A gen:Space nanopub may declare multiple role-predicate assignments inline in its assertion — gen:hasAdmin, has-event-facilitator, has-event-organizer, participatedAs*, etc. The extractor was only emitting a gen:RoleInstantiation for the gen:hasAdmin triples; everything else was silently dropped because gen:Space nanopubs aren't auto-typed with back-compat role predicates (only single-triple-assertion nanopubs are).

Symptom: spaces relying on inline role declarations (the 3pff FIP/M4M templates publish all roles in one gen:Space nanopub) end up with admins-only members in consumers. Found while migrating nanodash to query the spaces repo directly (knowledgepixels/nanodash#468) — FIP.38.T.8 has 3 facilitators, 1 assistant, and 1 organizer declared inline; before this fix none of them reach npa:spacesGraph.

Changes

• SpacesExtractor.emitSpaceEntry now calls a new emitInlineRoleInstantiations(np, ctx, spaceIri, out) helper after the admin-RI emission. It scans the assertion for any back-compat role predicate (excluding gen:hasAdmin, which is the trust seed and handled separately), groups by predicate, and emits one gen:RoleInstantiation per (predicate, direction) pair with multi-valued npa:forAgent — same shape as the admin path.
• Subject collision avoidance: a new SpacesVocab.forRoleInstantiation(artifactCode, discriminatorHash) overload mints npari:<artifactCode>_<predicateHash>. The admin RI keeps the unhashed npari:<artifactCode> subject (no behavioural change there).
• BackcompatRolePredicates: adds has-event-organizer (INVERSE). It's actively used by the 3pff FIP templates but was missing from the direction map.
• Test: extract_spaceWithInlineRoleTriples_emitsAdditionalRoleInstantiations covers admin + INVERSE-inline + REGULAR-inline emission in one gen:Space nanopub.

Test plan

• mvn test — 214 pass, 0 fail (including the new test)
• After deploy, FIP.38.T.8 (and other 3pff FIP spaces) will surface facilitators/assistants/organizers through the spaces repo. Verifiable via:

  SELECT (COUNT(?ri) AS ?n) WHERE {
    GRAPH npa:spacesGraph {
      ?ri a gen:RoleInstantiation ;
          npa:forSpace <https://w3id.org/fair/3pff/FIP.38.T.8> .
    }
  }
