Original exit flow composed with recovered intermission children

RE-842. Reproduce with python3 scripts/analyze_qvm_intermission_flow.py; focused validation: cargo xtask test-group intermission-flow. Machine report.

150 continuous 7805 fixtures now execute actual tie, readiness, begin-transition and exit-log children on shared world memory with separate child frames. Independent policy and nested ABI checks cover conflicting gates, client mutations and publication intentions. Lower-level next-map/respawn/camera/I/O and allocation still remain captured.

Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
