Streamline STM32 Schematic Layout

I have an existing STM32 schematic that is functionally sound but cluttered with legacy connectors and headers that are no longer part of the finished design. I want the schematic trimmed down so only the essentials remain. Please leave every programming and debugging header intact, preserve all power-input and power-output connections, and keep any interface that the final product still relies on. Nothing else should survive the cleanup—no spare GPIO headers, no test points that serve no purpose, and certainly no unused expansion connectors.

There is no need to touch the encoder pins or reroute anything; the task is purely a removal exercise. When you are done I expect:

• The updated schematic file in the same CAD format I will supply.
• A PDF printout for quick review.
• A short change log so I can verify what was deleted.

Clean, accurate work is the priority; the leaner the diagram, the easier our next PCB spin will be.
