Fix schematic: restore all wire connections, separate 3V3 from GND

- Re-connected all pins using pin-snapped connect_to_net (U1, U2, U3, J1, Q1, all passives)
- Fixed: 3V3 was shorted to GND by overlapping labels 0.47mm apart
- Replaced batch_connect labels (off-grid) with pin-exact connect_to_net labels
- Verified: 15 clean nets with no GND/3V3 contamination
- Nets: 3V3, CC1, CC2, CFG1, CFG2, EN, GATE, IO0, USB_DN, USB_DP,
        VBUS, VBUS_SENSE, VDD_CH224, VOUT, GND
