Emily Boudreaux 6b57738330 docs(docs): built docs 
Note for now much of the docs is LLM written. This was done to save time and focus on code development. The docs have been LOOSLEY reviewed. However, the code itself has been either fully written by hand or fully reviewed. Therefore, the docs should at the moment be seen as a loose resource rather than authoratiative (and this is on top of the general ability for docs to drift)

Couple scalar density and potential responses, then correct every shape and global constraint together.
Potential responds first and its force contribution then adjusts density. The existing dense border retains surface-\/to-\/field and field-\/to-\/surface responses, including the mean radius mode; shape has no separate mass inverse. Density uses its diagonal without regularization because its pressure-\/force Jacobian includes drift and need not satisfy the positive-\/diagonal contract of the elliptic AMG strategy used for potential. \begin{DoxyNote}{Note}
The dense border stores one field response per shape/global coordinate and a square border matrix. This default targets bounded surface catalogs; large nodal surfaces require an explicitly chosen scalable recipe.
This is an approximate inverse, not a guarantee that the physical constraint Schur system is nonsingular.
