Jet gains a last field condition='velocity'. 'pressure' raises
NotImplementedError in __post_init__ before profile/amplitude validation, so a
pressure jet never reaches surface_link_velocity, tables or kernels; unknown
values raise ValueError. Amplitude stays a lattice velocity (not a flow rate);
no pressure units, field reuse, tables or kernel changes are introduced.

(cherry picked from commit fbf6f1d122)
surface_link_velocity (the shared host check used by CurvedLinkSoA,
ObjectManager sync, prepare_fine_boundary and FixedPatchStepper) now
rejects a jet whose selected cut links carry more than one body id, at
any amplitude, before uploads. Identity is the scene-wide body id of the
physical cut-link list, so one body spanning storage blocks stays valid.
No body selector; empty-selection semantics unchanged.
Tests: two bodies under one jet rejected (amplitude 2e-3 and 0) on the
Simulation/manager path and on the fine path; separate jets on separate
bodies accepted on both; one fine body crossing 2x2 block seams accepted.

Move surface_link_velocity (pure host code) from lbm/curved_links.py to
body/jets.py, re-exported by curved_links, so refinement.py can reuse it
without importing PyCUDA. prepare_fine_boundary now runs the same
assignment validation as the steppers when jets are given, rejecting
jet-vs-SurfaceActuation overlap (root's C(12.25,12.25) R2.15 case) as
well as empty/overlapping jets. Test the overlap and a disjoint pair.

Sector/Tube/Radial store origin as a validated float 2-tuple, so caller
lists/arrays cannot change a registered definition. Simulation.set_body
rejects nonzero motion for bodies with Jet-driven links once initialized
(before initialize the sync-time stationary check applies).
prepare_fine_boundary accepts jets in the same coarse cell-edge frame as
fine objects, records read-only FP64 edge-frame hits (FineBoundary2D
.curved_hits, default None) and rejects empty or overlapping selections
before CUDA. FixedPatchStepper wiring is not included.

Replace fine_hits_to_physical with fine_hits_to_edge_frame (patch
cell-edge frame, coarse centers at I+1/2, as FixedPatchStepper uses) and
edge_to_node_frame (Simulation integer-node frame, shift -1/2). Test one
physical circle through both frames: fine hits converted to node frame
lie on the Simulation circle and one node-frame Jet selects the same arc
on coarse and fine links; relabelling without conversion is detected.

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.

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.
