Fix cli/tests/scripts/test_similarity.sh

Fix failing `task test:cli:sh` cmd `TEF_API_KEY=$OPENROUTER_API_KEY ./cli/tests/scripts/test_similarity.sh`, which has some issue with discovering MCP servers:

```
[INFO] Raw similarity analyze result:
✗ HTTP error from mcp-tef server
  Status: 422 - {"error":"ValidationError","message":"At least 2 tools required for similarity analysis, got 0","details":{}}
```
