Summary

• add an exact STM32H562RGT6 library entry with local LQFP-64 footprint and STEP model
• correct MS5611, LIS2MDL, ADXL375, and LSM6DSOX symbol pin names and electrical types against manufacturer datasheets
• update the MS5611 and LIS2MDL footprints to current KiCad 10 package geometry
• stack hidden MS5611 pin 5 on CSB pin 4 so footprint pads 4 and 5 share the CSB net

Validation

• library validator passes
• all 27 unit tests pass
• symbol pin sets match footprint pad sets for all five components
• all affected symbols and footprints render successfully in KiCad 10
