feat(phase-3.1): agent entity types + metadata structs

EntityType enum extended with 3 agent types:
  - AgentPrompt: track prompt templates, usage, quality
  - AgentSkill: track learned capabilities, success rate, latency
  - AgentDecision: track decisions, reasoning, outcomes

New module: agent_entity.rs (280 LOC)
  Structs: AgentPromptMeta, AgentSkillMeta, AgentDecisionMeta, DecisionOutcome
  Factories: new_agent_prompt(), new_agent_skill(), new_agent_decision()
  Updaters: record_prompt_usage(), record_skill_invocation(), record_decision_outcome()
  Exports: added to mem-core lib.rs

Tests: 8 new (prompt, skill, decision, outcome, usage stats,
       invocation stats, round-trip, serialization)
Build: cargo build --release clean
Suite: 174 lib tests pass

-# Poimen Memory System
-
-## Project Status
-
-**Architecture**: Temporal Knowledge Graph for Agent Memory (Zep paper alignment — arXiv:2501.13956)
-
-**Current**: Ingest pipeline with LLM entity + fact extraction working E2E. Deployed to K8s.
-
-### What Works
-- ✅ HTTP server (actix-web) with 15+ endpoints
-- ✅ LLM entity extraction (LlmEntityExtractor) — extracts person/tool/concept/org entities
-- ✅ LLM fact extraction (LlmFactExtractor) — extracts relationships between entities
-- ✅ Reasoning model support — strips `<think>` tags, markdown fences
-- ✅ Ollama + vLLM + OpenAI-compatible API support
-- ✅ Entity persistence to pgvector (memory_entity table)
-- ✅ Edge persistence (memory_edge table with temporal fields)
-- ✅ Graph query endpoints (entities, edges, BFS traversal)
-- ✅ Visualization (React Flow JSON, force-directed layout, SSE streaming)
-- ✅ JWT auth (Authentik OIDC) with RBAC
-- ✅ K8s deployment (CNPG postgres, ConfigMap, SOPS secrets)
-- ✅ CI: PR builds push :SHA tag, main merges retag :latest
-- ✅ 781 tests passing
-
-### Deployment
-- **Namespace**: `poimen`
-- **Image**: `forgejo.riotpiao.com/riotpiao-poimen/poimen-memory:latest`
-- **DB**: CNPG cluster `memory-db` (pgvector)
-- **LLM**: `reasoning-predictor.llm-serving.svc.cluster.local` (ornith:35b / qwen2.5:3b)
-- **Auth**: Authentik OIDC (`MEM_AUTH_MODE=none` for dev)
-- **Registry**: Forgejo container registry (FORGEJO_REGISTRY_USER/TOKEN secrets)
-
-### Key Env Vars
-```
-DATABASE_URL          postgresql://...
-MEM_AUTH_MODE         none|jwt|apikey
-LLM_ENDPOINT          http://localhost:11434/v1/chat/completions  (Ollama)
-LLM_MODEL             qwen2.5:3b | ornith:35b | reasoning
-LLM_API_KEY           (for authenticated LLM APIs)
-MEM_API_KEY           (server API key, fallback "test-key")
-OPENSEARCH_HOSTS      (optional, hybrid search)
-GATEWAY_URL           (optional, external queue)
-```
-
-## Rules
-
-1. **No progress markdown files.** Track via Forgejo issues + PRs only.
-2. **Obsidian vault repo**: `ssh://[email protected]:2222/rock/poimen-obesdient-memory.git`
-3. **Secrets via KSOPS**: Age-based SOPS encryption. Never commit plaintext.
-4. **Tea CLI**: `poimen` login has API token `1f717a00134f17c9d2d656c620b955e03ea41276`
-
-## Architecture (Zep Paper §2)
-
-### Three-Tier Knowledge Graph
-```
-Episode Subgraph (raw messages)
-  → Entity Subgraph (extracted entities + facts/edges)
-    → Community Subgraph (clusters, planned Phase 4)
-```
-
-### Ingest Pipeline (4 stages)
-1. **Entity extraction** — LLM extracts named entities with type + summary
-2. **Deduplication** — HashSet on normalized name
-3. **Fact extraction** — LLM extracts relationships between entity pairs
-4. **Contradiction detection** — pre-filter + review queue
-
-### Retrieval (3 methods, §3)
-- Cosine semantic similarity (pgvector HNSW)
-- BM25 full-text (OpenSearch, optional)
-- BFS graph traversal (depth 1-3)
-
-### Extractors
-- `LlmEntityExtractor`: calls LLM_ENDPOINT, parses JSON, handles reasoning models
-- `LlmFactExtractor`: takes entity list + text, extracts edges between known entities
-- `WikiLinkFallbackExtractor`: pattern-matches `[[wiki links]]` (no LLM)
-- `SimpleFactExtractor`: verb pattern matching (no LLM)
-- Selection: LLM extractors when `LLM_ENDPOINT` set, else fallbacks
-
-### LLM Response Cleaning
-`clean_llm_response()` handles:
-- `<think>...</think>` blocks (reasoning models)
-- Markdown code fences (```json ... ```)
-- Array responses (wrap in `{"entities": [...]}`)
-- Extract first JSON object from mixed text

-# Kubernetes Troubleshooting Guide
-
-## Port Conflicts
-
-When a port conflict occurs on port 8080, check for existing services:
-
-```bash
-kubectl get svc --all-namespaces | grep 8080
-```
-
-### Common Causes
-
-1. Multiple services binding to same NodePort
-2. Host network pods conflicting with node services
-3. Ingress controller port overlap
-
-## CrashLoopBackOff
-
-Pods enter CrashLoopBackOff when the container exits repeatedly.
-
-### Diagnosis Steps
-
-1. Check pod logs: `kubectl logs <pod> --previous`
-2. Check events: `kubectl describe pod <pod>`
-3. Check resource limits: memory/CPU constraints
-4. Check liveness probes: incorrect health check paths
-
-### Resolution
-
-- Increase memory limits if OOMKilled
-- Fix application startup errors
-- Adjust probe timing (initialDelaySeconds)
-- Check environment variable configuration
