Counterpart of dimensionalOS/dimos#3477 (consumed by dimensionalOS/dimos#3391, whose pin points at this branch).

Drops the imu_* config fields; with enable_imu on the module now waits for a sensor_msgs.ImuInfo message the way it waits for camera_info, reading the Allan constants, rate, and IMU frame from it (frame previously came from the first Imu sample). ImuInfo.hpp is vendored lcm-gen output under src/vendor until dimos-lcm ships the type — schema and pinned fingerprint live in the dimos-side ImuInfo.py.

The imu_* config fields are gone; when enable_imu is on the module now
waits for a sensor_msgs.ImuInfo message the way it waits for camera_info,
and reads the Allan constants, rate, and IMU frame from it. The frame
previously came from the first Imu sample; the info message is now the
single source. ImuInfo.hpp is vendored lcm-gen output under src/vendor
until dimos-lcm ships the type.
