A failed MovingCircle.advance now calls the owner hook, so the Simulation
is marked failed (Jet lifecycle) and refuses run/step/sync until close().
Adds host tests for set_body routing on real objects, initialize band and
mode rejections before mutation, exclusion from static link packing, and
the Simulation failure lifecycle. Contract status line updated for S1.

Carries the reviewed S0 draft into the S1 branch and fixes: applied stores
only the offset, explicit 'pending is not None', reject a hold target with
nonzero translational velocity, single Euclidean 0.5-cell bound.
