Jet is a frozen dataclass; with_amplitude returns a validated copy, so
region/field/profile cannot drift from the cached per-link shapes and
amplitude cannot bypass validation. CurvedLinkSoA.set_jet_amplitude and
Simulation.set_jet_amplitude replace the Jet (Simulation also updates the
registered list so later geometry syncs keep the amplitude). Reject
non-finite hits; document edge rule (|s|<1 exclusive, radial/along
bounds inclusive). Fix the clipped-q test selector to receiver (9,5)
dir 8, as in test_surface_actuation.

ObjectManager.jets holds scene-level Jets. build_compact_lists_for
collects true FP64 hits (SimObject.get_curved_list hits_out) row-aligned
with the cut-link columns; BodySyncPlan carries them as curved_hits, and
sync_to_gpu / apply_sync_plan / the pre-sync check pass jets+hits to
assign_surface. Jets require D2Q9/FP32/unshifted/double_buffer and may
only drive links of stationary bodies. Simulation.add_jet (before
initialize) and set_jet_amplitude (velocity column re-upload only);
save_checkpoint refuses scenes with jets. Fine-path wiring not included.

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.
