Just an FYI for contributors: The tentative schedule for INAV 10 is to have a full release in mid December. That means RC2 needs to be in early to mid November, which places INAV 10.0RC1 at September 1. Please plan to have any new features for INAV 10.0 ready for RC1 no later than September 1. After that, 10.1 will follow about six to seven months later. |

Adds droneCANBusOffCount to the blackbox S-frame, sourced from the existing dronecanGetBusOffCount() counter, so intermittent CAN bus faults are diagnosable from flight logs instead of requiring a live `dronecan` CLI session. TEC/REC/LEC/state and RX-drop-count were considered and dropped/deferred (see PLAN.md) as poor fits for the slow frame's throttled, change-triggered sampling model.

Dependency
This branch is stacked on #11607 (DroneCAN: Fix H7 FDCAN and F7 bxCAN driver configuration), which is still open. Only the most recent commit (
dronecan: log cumulative bus-off count to blackbox slow frame) is new here — the diff currently includes #11607's commits too, until that PR merges and this one rebases ontomaintenance-10.xdirectly.Do not merge before #11607.
