Complete leaderboard joint thresholds sentinel updates and ties

RE-773. Reproduce with python3 scripts/analyze_qvm_leaderboard_selector.py; validate with cargo xtask test-group leaderboard-selector. See the machine report.

Recovered complete284610 with actual278587 and corrected repeated-call reentry over77 configurations. All nine metrics jointly gate a candidate, including sentinel-valued inactive fields; updates preserve inactive sentinels. All-sentinel records never select despite candidates passing gates. Scan order and strict ties are explicit. Invalid keys, live-null clients and original runtime parity remain open.

No original executable/full VM/native world collision or rendering runs. Supplied callback/native responses and fixture domains remain explicit; complete macOS/Linux Rust/Bevy/Solari gameplay remains open.
