feat: Memory Service API ready for deployment — Vault JSON endpoints + Hybrid search

Browse Source 
API Changes (crates/mem-cli/src/http_server.rs):

✅ Vault Endpoints (JSON API):
  - GET /memory/vault → {projects: [...]}
  - GET /memory/vault?project=X → {project: X, files: [...]}
  - GET /memory/vault/{proj}/{file} → {metadata: {...}, content: '...'}
  - YAML frontmatter parsed to JSON metadata
  - Auth: JWT on all endpoints

✅ Search Endpoints:
  - GET /memory/query?method=semantic → pgvector only (60% weight)
  - GET /memory/query?method=hybrid (default) → pgvector + OpenSearch (fallback to semantic)
  - Hybrid score: 0.6*semantic + 0.4*lexical
  - Limit: top-10 results (default)

✅ AppState Extended:
  - opensearch_client: Option<Arc<OpenSearchClient>>
  - Initialized from OPENSEARCH_HOSTS env var (optional)
  - Graceful fallback if OpenSearch unavailable

✅ Handlers Updated:
  - vault_browser_handler() → returns JSON projects list
  - vault_project_tree() → helper for file tree generation
  - vault_project_handler() → GET /{project} → file tree JSON
  - vault_file_handler() → GET /{project}/{file} → JSON with metadata + content
  - query_handler() → hybrid search with semantic fallback

K8s Manifests (k8s/infra/databases/opensearch.yaml):

✅ OpenSearch StatefulSet:
  - 2 replicas for HA cluster (opensearch-0, opensearch-1)
  - Image: opensearchproject/opensearch:2.11.0
  - Services: opensearch (headless), opensearch-internal (ClusterIP 9200)
  - ConfigMap: opensearch.yml with cluster settings
  - PVC: 30Gi per pod (Longhorn storage class)
  - ServiceAccount + NetworkPolicy (Memory Service only)
  - Init container: set vm.max_map_count=262144
  - Probes: liveness (60s), readiness (30s)
  - Resources: 512Mi-1Gi memory, 250m-500m CPU
  - Security: plugins.security.disabled (K8s network isolated)

✅ Updated kustomization.yaml:
  - Added opensearch.yaml to resources

Documentation:

✅ docs/API_VAULT_ENDPOINTS.md (10KB):
  - Complete API reference with examples
  - Architecture: semantic (pgvector IVFFlat) + lexical (OpenSearch BM25)
  - Fusion strategy: weighted linear combination (60/40 split)
  - DNS records for vault.riotpiao.com + memory.riotpiao.com
  - Ingress configuration (dual-domain routing)
  - Frontend integration examples (React/Vue)
  - Fallback behavior (graceful degradation)
  - Performance tuning (IVFFlat lists, OpenSearch shards)
  - Security: JWT validation, rate limiting, field-level ACL (future)

✅ docs/DEPLOYMENT_CHECKLIST.md (8KB):
  - 5-phase deployment plan (API ready, OpenSearch, DNS, Testing, Frontend)
  - Step-by-step deployment commands
  - Testing procedures for vault + search endpoints
  - Troubleshooting: OpenSearch not found, cluster red, JWT validation
  - Monitoring metrics + dashboard queries
  - Fallback scenarios + error codes

Environment Variables:

- OPENSEARCH_HOSTS (optional, e.g., "opensearch-internal.poimen.svc.cluster.local:9200")
  - If unset: hybrid search disabled, falls back to semantic
  - CSV list supported: "host1:9200,host2:9200"

Deployment Summary:

1. ✅ API code ready (JSON endpoints, fallback to semantic if OpenSearch unavailable)
2. ✅ OpenSearch K8s manifests (StatefulSet + networking)
3. ✅ Documentation (API reference + deployment guide)
4. ⏳ Ready to: kubectl apply -k k8s/infra/databases/

Backward Compatibility:

✅ Existing JSON endpoints work without change
⚠️ HTML endpoints replaced with JSON (breaking change for old clients)
✅ Graceful fallback: hybrid search → semantic if OpenSearch missing
✅ Rate limiting preserved on all endpoints

Testing Ready:

- Vault tree endpoint testable after deployment
- Hybrid search testable once OpenSearch cluster ready
- All endpoints require JWT from Authentik
- Load test script provided

Next: Deploy OpenSearch + test against vault.riotpiao.com
