Me Here adc92c7c02 PM_K-1 hardware: fix the 2 real import issues (crystal footprint + USB shield error) 
- Crystal Y1: footprint was a 4-pad type (Crystal_SMD_3225-4Pin) on a 2-pin symbol ->
  pads 3/4 had no symbol pin. Switched to Crystal_SMD_2012-2Pin to match (set to the
  chosen crystal's real footprint at BOM time; ground the case pads if 4-pad).
- USB-C J5: the library symbol's shield pin "S1" mismatches older KiCad footprints that
  name the shell pads "SH" -> "pad S1 not found" ERROR. Dropped the shield net from the
  schematic; the USB shell->chassis is now a layout-time tie (direct or 1Mohm||cap),
  which is version-independent and standard practice. Error resolved; ERC 0.

The remaining ~46 import warnings are HARMLESS: "no net for pad N" on intentionally
unconnected pins (spare RP2350 GPIOs, unused relay NO contacts, unused ULN2003/74LVC14
channels, IC NC pins) -- expected on any board, nothing to fix.

"""PM_K-1 FULL BOARD (SKiDL): the whole core board as one netlist for PCB layout.
Run INSIDE the EDA container:
cd hardware/eda && ./run.sh python3 ../eda/circuits/board.py
Outputs ERC + hardware/kicad/board.net (the master netlist to import into Pcbnew).
This re-implements every block (power, MCU, audio chain, RTC, MIDI-DNP, interconnects,
SIG/CLIP-DNP, speaker-DNP) with SHARED net objects and NO forced reference designators --
SKiDL auto-numbers them, so refs are unique board-wide (the per-block files have colliding
refs by design; this file is the single integrated source of truth, like audio_chain.py is
for the audio stages). All IC pinouts datasheet-verified in the per-block files.
MCLK-LESS: the PCM5102A SCK is tied to GND (internal-PLL operation) -- no audio oscillator.
