GL-X3000 r6: Catching Up With Upstream Without Breaking the Modem

TL;DR: I rebuilt Jeeves — my GL-iNet GL-X3000 5G backup uplink — on the latest OpenWrt 25.12, jumping the kernel from 6.12.85 to 6.12.94. My 20 device-enablement commits rebased cleanly onto 155 upstream commits. One build trap cost me a rebuild. Then I flashed the running router and checked the telemetry to confirm the 5G leg came back unchanged. The image is jeeves-r6 on the releases page .
