Snapshot WIP: solver HP epic progress, BPHX/HX physics, BMAD skill refresh.

Capture uncommitted solver robustness work (regularization, domain errors, linear solver lifecycle, tube DP/MSH), web workbench updates, and synced BMAD skills across IDE agent folders before starting BPHX pressure-drop.

 **Cross-cutting intent — walk both surfaces with the user:**
 - Every workflow a given agent runs → agent surface (e.g. `bmad-agent-pm.toml` with `persistent_facts`, `principles`).
