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)
initialize(coarse_g=..., fine_g=..., child_g=...) raised TypeError after the
switch to *level_g. A small entry adapter (_initial_levels) maps either the
positional per-level form or the original names to one per-level tuple and
rejects mixed or incomplete forms with TypeError before any state check.

Schedule test drives _pairs[i].explode/coalesce and patches _advance(index,
buffer) for the stale L1->L2 feed mutant; remap rejection test patches
_boundary_hosts entries and hierarchy.pairs instead of the read-only views;
the GPU launch-failure test patches _pairs[0].explode. Assertions unchanged.

build_hierarchy(cfg, [], wall_aware=True) left both base wall rows ACTIVE;
the refined path already marked them OUTER. Add the regression test.

The constructor builds lbm.hierarchy geometry, per-level layouts, kernel
configs, boundaries and leaf masks as lists, then one _build_level per level
and one _build_pair per adjacent pair. step() runs _hop(0): a child explodes
from its parent's hop source and advances twice, then the parent gathers
halos, stages receiver-local restriction, applies BFL and steps. Launch
sequence for existing two/three-level cases is unchanged; depth >= 4 works
for fully blocked hierarchies with bodies/Jets on the finest level.
New keywords refinements/level_blocks/level_objects/level_jets (L0 included);
legacy keywords are normalised by _legacy_levels and are mutually exclusive
with them. The dense two-level path stays as an isolated branch in _hop
(fused PatchCoarseStep root, dense fine BFL). Removed _child, _middle_kind
storage, _explode/_coalesce/_ghosts/_donors/_targets/_children,
_advance_child, _blocked_fine_boundary and _remap_blocks; existing public
attributes and the private names tests still read are thin read-only views.

lbm/hierarchy.py loops the existing pair logic (FixedPatch2D/FixedPatchSet2D
for L0->L1, nest_patch/nest_patch_set for deeper pairs, _middle_config for
the per-level config chain) and returns validated per-level configs, pair
tables and composed kinds for any depth. Legacy scalar window forms are
accepted so existing public shapes are unchanged. Validates each config copy
because LBMConfig.omega is only computed by validate(). Not yet used by the
stepper.

Pure move of blocked_fine_tables, blocked_kind, blocked_base_tables,
_BlockedBoundary and _prepare_blocked_boundary out of the pycuda-importing
refinement_stepper into a numpy-only module, so CPU tests can import them
directly. refinement_stepper re-exports the public names; no behaviour change.
