- _exchange_spacing/_exchange_centers (two more per-level lists, only read
for levels that have a boundary) become _BlockedBoundary.spacing/centers.
- _level_blocks dropped: remap_finest reads each layout's own .block.
- _device_boundaries -> _boundaries: the record holds host geometry, tables,
Jets and device handles, so 'device' was misleading (the old host-only
_boundaries list no longer exists). Tests migrated mechanically.
Remaining per-level lists (_layouts, _level_cfgs, _leaf, _state, _boundaries)
are the immutable construction plan, built before the memory preflight and
kept after close; _levels holds device handles only and is cleared on close.

The removed _boundaries list made the two body-reject patches no-ops.
Inject them via _device_boundaries (level-2 record with foreign host
geometry; non-None level-1 record). set_jet_amplitude docstring names
the public jets view.

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.
