Manifold Shell - The Square: Manifold-Content-Surface-Observation
===================================================================
Manifold Shell for cubesquare_standalone.

This shell implements the manifold system where:
- Manifold defines what can be observed
- Observation defines the manifold's surface
- Neither exists without the other (mutual definition)
- This IS self-identity

Commands:
    status          - Full system status
    agents          - List agents with I-Logic states
    square          - Show the manifold square diagram
    generate        - Generate new agent from need
    earth           - Earth Prime manifold status
    flip            - LLM weight flip demo (O(1) inference)
    vector          - Vectorized agent cycle (no for loop)

The K5 centroid at 41.7 Hz is where new agents spawn.
