New essay and interoceptive alignment

Two substantial additions to the project:

Interoceptive / Stress-sharing alignment has been added to the Alignment Atlas. It describes systems in which local stress, need, or error is made available beyond the component experiencing it, allowing burdens and resources to be redistributed across the larger system.

A new essay, Transformational Alignment: The Economy as Singleton, asks what kinds of alignment architectures can scale to very large systems. It argues that economies achieve extraordinary scale partly by allowing their higher-order organization to transform around heterogeneous components rather than continually forcing those components toward a fixed macro-target.
