Tugger AMR replay: protective fields ON vs OFF

Recorded missions from a ROS 2 Jazzy simulation (Nav2 + C++ protective field monitor + VDA 5050 bridge). Same seed = same people at the same moments. Simulation only; the field monitor is not a certified safety function. Code and measured results: github.com/pavanyadava007/amr-tugger-nav
