v5.4.3 — Telemetry

The pit wall finally gets its telemetry feed. The garage has had the gauges wired at the provider end for months — tonight the sensors went in: real-device speed readings and visit counts now flow from every page to the dashboard, so decisions about what to tune next come from how the garage actually drives on your phone, not from how it feels on ours. Same night, the perimeter got its first proper fencing — automated attack patterns now meet a challenge at the door — and the vault's rewind window stretched from six hours to seven days. None of it changes a single pixel; all of it means the crew sees trouble sooner.
