Quick session finishing up the PCB layout wiring.

Fixed a routed trace that was cutting straight through the ESP32-S3’s antenna keepout area — would’ve wrecked WiFi/BT range if left in
Repositioned SW1 (boot/flash button) away from the OLED header — it was sitting close enough that the actual 44x36.5mm OLED module body would’ve physically overlapped it
Cleared remaining DRC violations (via clearance issue near the EN net, drill size on U2’s thermal pad)
Board is now fully routed with 0 errors on DRC

Next: case design in Fusion 360 now that component placement is locked in.
