Relative pose angle publication and numeric flag sum

RE-664. Reproduce with python3 scripts/analyze_qvm_pose_publication.py; check with python3 scripts/test_qvm_pose_publication.py. The machine report retains source identity and bounded fixtures.

Actual33168–33388 writes flag96+(flag92>>1)+(flag100>>2) when argument48 is nonnull. This is addition of arithmetic right shifts, not a bitwise packed mask. It subtracts body from head and legs from body, repeatedly wraps each relative component with strict±180 comparisons, then publishes legs/body-relative/head-relative at output0/12/24. Absolute legs remain unnormalized. The source has no child calls here. Nonboolean flags are deliberate arithmetic probes, not asserted legal states; no asset-specific skeleton names or renderer conventions are inferred.

No original executable/full QVM/native collision/physics/rendering executes. Native responses and legal input domains are supplied or unverified where stated; full runtime/macOS/Linux Rust/Bevy/Solari gameplay remains open.
