Merge branch 'main' into fix/1436

- Add integration tests with real ChromaDB
- 8 integration tests for agent memory
- Tests actual storage, retrieval, and search
- Handles ChromaDB filter limitations gracefully
- Includes persistence testing across instances

Addresses issue #1436: [TEST] No integration tests with real ChromaDB

Tests added:
1. test_remember_and_recall: Store and retrieve memories
2. test_diary_writing_and_retrieval: Write and recall diary entries
3. test_wing_filtering: Test wing-based filtering
4. test_memory_persistence: Test persistence across instances
5. test_empty_query: Test empty query handling
6. test_large_memory_storage: Test storing many memories
7. test_memory_with_metadata: Test memories with metadata
8. test_create_with_chromadb: Test factory function

All tests use real ChromaDB instance with temporary storage.
Tests skip gracefully if ChromaDB is not installed.

-### WebSocket Pattern
-```python
-async def handler(websocket):
-    async for message in websocket:
-        # Process and broadcast
-        pass
-```
-
-### Portal Schema
-```json
-{
-  "id": "portal-id",
-  "name": "Display Name",
-  "portal_type": "game-world",
-  "destination": { "url": "...", "type": "harness" }
-}
-```
-
----
-
-## Security
-
-- WebSocket gateway binds to `127.0.0.1` by default
-- Optional token authentication via `NEXUS_WS_TOKEN`
-- Rate limiting on connections and messages
-- Branch protection on `main`
-- Provenance hash verification
-
-See `SECURITY.md` for full details.
