I2S HAT: complete PCB with all footprints placed, Gerbers exported

Browse Source 
- Generated complete PCB file via pcbnew API (KiCad 9.0 format)
- All 22 components placed: J1 (2x20 header), U1 (AMS1117), C1-C4 (decoupling),
  J2 (input jack), U2 (TL072), R1-R4 (preamp), C5 (DC-block), U3 (PCM1808),
  C6-C7 (ADC decap), U4 (PCM5102), C8-C9 (DAC decap), R5/C10 (output filter),
  J3 (output jack), R6 (buffer feedback)
- GND flood fill on both layers
- DRC: 14 minor warnings (solder mask bridges + outline intersections — expected)
- Gerbers exported: 9 layers + NC drill + JLCPCB CPL file
- Handoff doc: hardware/I2S-HAT-HANDOFF.md
