Original connect clear and session-branch caller

RE-912. Reproduce with python3 scripts/analyze_qvm_connect_session.py; focused validation: cargo xtask test-group qvm-connect-session. Machine report.

96 bounded173979 caller-path executions cover174081..174173 after userinfo/authentication: entity-client linking, actual6336-byte clear via modeled native memset, connecting-state/client-slot writes and the first-time OR new-session choice between actual247520 initialization and247219 restore. Both children execute recovered load/format/scanner policies. Uppercase team S below capacity is not the lowercase s shortcut. Authentication before the slice, post-branch normalization and native engine integration remain open.

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