Jet(region, field, profile, amplitude) with Sector/Tube regions,
Radial/Parallel fields and uniform/parabolic/quartic profiles. Selection
uses true FP64 hit points over all scene cut links, no body association.
Overlap between jets or with a SurfaceActuation aperture is rejected.
CurvedLinkSoA caches unit-amplitude shapes; set_jet_amplitude rewrites
and re-uploads only the surface-velocity column. SurfaceActuation.as_jet
is the legacy adapter (equivalence measured in tests). Kernel and SoA
geometry columns unchanged. Manager/Simulation/fine-path wiring pending.
