XY-898: [ELF benchmark vNext P3] Promote first-generation OSS memory baselines into real-world adapters

[yvette-carlisle]

Summary

• Adds first-generation OSS adapter scenario judgments with typed statuses and ELF position summaries (wins, ties, loses, untested).
• Updates agentmemory, mem0/OpenMemory local OSS, memsearch, and claude-mem evidence so basic baseline smoke is separated from real-world/history/UI/continuity claims.
• Refreshes benchmark reports, measurement audit artifacts, and strength matrix wording around the 2026-06-11 scoped baseline evidence.

Validation

• cargo test -p elf-eval --test real_world_job_benchmark --all-features external_adapter -- --nocapture
• cargo make real-world-memory
• cargo make real-world-memory-live-adapters
• ELF_BASELINE_PROJECTS=ELF,agentmemory,mem0,memsearch,claude-mem cargo make baseline-live-docker completed and preserved typed non-pass competitor states
• JSON/report consistency checks with jq -e, stale-token search, and git diff --check
• cargo make fmt
• cargo make lint-fix
• cargo make checks
