Expose entity resolution response schemas to JSON object providers

+## Schema visibility fix (prompt protocol v2)
+
+New resolution runs freeze `protocol_version = 2` in their input artifact. Both
+planning and assessment include the output schema in the user message, so
+providers configured with `response_format = "json_object"` can see the required
+fields. That provider mode only requests JSON; it does not transmit the internal
+request schema. Protocol v1 omitted that message field. Existing v1 artifacts
+retain their original request construction and prompts for immutable replay.
+
+The first live entity-resolution trial exhausted planning validation: two
+`LLM_OUTPUT_SCHEMA` results and one `LLM_INCOMPLETE_OUTPUT`. No lookup was
+executed. The error records do not retain rejected response bodies or the exact
+incomplete finish reason, so they cannot establish each response's detailed
+cause. Do not retry that exhausted case unchanged; use the fresh trial below.
+
+A corrected trial is prepared at `service-data/trials/entity-resolution-schema-20261015`

+Return exactly one resolution for each plan search, in order, with zero-based search_index.

+For ambiguous or no_match, candidate_id must be null. no_match means the scoped name query returned
+no rows, never that an entity is missing from the running world. Results reflect a configured snapshot.
+Database ID/name is a technical fact; a contextual role assignment is a model association, not causation.
+Never infer absent spawns, diagnose a defect, exclude quest giver scripts as possible contributors,
