Implements the cached state machine: detect FiffInfo changes (channel list, bad-channel list, dig-point list), rebuild the channel selection, project the SSP matrix into the good-channel subspace, apply it to the data buffer and rebuild the InvSensorSet from the updated coil list. Exposes pre-projected data, projectors, sensors and digitised coil positions as read-only accessors consumed by InvHpiFit.
