Materialize service-native Dreaming readback

[yvette-carlisle]

Summary

• add a Docker-contained service-native Dreaming readback benchmark command for memory_summary, proactive_brief, and scheduled_memory
• materialize derived artifacts through ElfService add_note/list readback while separating full source-ref audit from scored non-trap evidence ids
• check in service-native report/materialization snapshots and documentation for XY-986

Benchmark

• cargo make real-world-memory-service-native-dreaming: 9 pass, 0 wrong_result, 2 typed XY-930 blockers, 22/22 evidence/source-ref/quote coverage

Validation

• cargo make fmt
• cargo make lint-fix
• cargo test -p elf-eval --test real_world_job_benchmark service_native_dreaming_readback_report_materializes_public_jobs -- --test-threads=1
• cargo make real-world-memory-service-native-dreaming
• cargo make check
