Opaque/mask draws sharing a pipeline and bind set become rows of one
persistent `draws.<id>` indirect array (32-byte indexed commands,
geometric capacity, inactive tail zeroed) drawn by a single graph pass,
so the graph holds one pass per bucket instead of one per mesh.
Transmission and blend draws stay direct and ordered after the buckets.
Scene requires the indirect-first-instance feature. Compiles re-assert
the bundle block when they start, since an earlier switch in the queue
clears the one set at enqueue time.

Geometry becomes a span in a single 80-byte interleaved `vertices` array
plus a span in a single `indices` array, allocated through the core's
span allocator instead of one arena array per mesh attribute. Draws are
always indexed with baseVertex; face-material overrides emit one draw per
run of same-material faces rather than one per face. Vertex data is
validated as a whole before any span is touched, same-geometry mutations
are serialised, and render signal 4 is held across a span change until
the graph reflecting it is published. Sibling arrays grow to the primary
array's capacity in one batch; reserve() takes vertex/index totals.
