fix: MCP tools migrated from StateVector V1 to StateTensor V2

- identity_tools.py: rewritten to read StateTensor (8x1024 named vectors)
  instead of StateVector (single 1024-dim). Uses CATEGORY_TO_DIMENSION mapping.
- mcp_server.py: get_state_vector renamed to get_state_tensor
- __init__.py: updated exports

Now returns S(30) with architecture v2_tensor instead of S(2) from V1.
