* test: add StickYaw unit test for unaided_yaw NaN transition bug
Adds a functional gtest that verifies the yaw setpoint does not jump
discontinuously when unaided_yaw transitions from finite to NaN.
Reproduces the bug fixed in #25710.
* test(StickYaw): clarify unaided_yaw NaN root cause in test comment
NaN originates from corrupted IMU delta_angle propagating through
OutputPredictor::calculateOutputStates() Euler extraction.
* Fixes potential bug if unaided yaw becomes nan during execution:
if unaided yaw becomes nan during execution the yaw correction would jumpt to 0 causing a large jump in yaw
the change removes this jump by holding the current yaw correction instead
* Remove Python extra paths from settings.json
Removed Python extra paths from VS Code settings.
