Rev 0.2: Major hardware improvements and production readiness

Hardware Improvements (Thanks to shx for schematic cleanup):
- Clean up schematic organization and structure
- Set CAN transceiver Silent pin to GND for stability
- Add status LEDs (yellow: 24V/5V/3.3V, green: MCU PB4)
- Replace jumpers with solder jumpers on bottom side
- Add jumpers to output PFETs for permanent-on without firmware
- Add robust test points for 5V/GND load testing
- Add optional heatsink for DC/DC converter on bottom
- Add 10µF capacitor for MCU on 3.3V rail

Component Optimizations:
- Replace 30kΩ with 33kΩ basic part for simplified BOM
- Change DC/DC feedback: 15.5kΩ15kΩ (new output: 5.1V)
- Upgrade CAN ESD protection: NUP2105LPESD1CAN
- Increase CAN termination resistor footprint: 04020603
- Switch USB hub supply from 5V to 3.3V per datasheet

Production Ready:
- Add all LCSC part numbers and rotations
- Generate complete production data package
- Improve PCB layout and button placement
- Create comprehensive changelog documentation
