add nocmem: auto memory recall + ingest via NuoNuo hippocampal network
- nocmem Python service (mem/): FastAPI wrapper around NuoNuo's Hopfield-Hebbian memory, with /recall, /ingest, /store, /stats endpoints - NOC integration: auto recall after user message (injected as system msg), async ingest after LLM response (fire-and-forget) - Recall: cosine pre-filter (threshold 0.35) + Hopfield attention (β=32), top_k=3, KV-cache friendly (appended after user msg, not in system prompt) - Ingest: LLM extraction + paraphrase augmentation, heuristic fallback - Wired into main.rs, life.rs (agent done), http.rs (api chat) - Config: optional `nocmem.endpoint` in config.yaml - Includes benchmarks: LongMemEval (R@5=94.0%), efficiency, noise vs scale - Design doc: doc/nocmem.md
