PM_K-1 hardware: integrate audio chain into one netlist (dedup shared parts)

Browse source 
circuits/audio_chain.py wires stages 1/1b/2/3/4 with shared nets and deduplicated
parts: ONE OPA1612 (U4) does both the Stage-2 filter (A) and Stage-3 summer (B);
ONE ULN2003 (U6) drives all three relays (K1 select, K2 mute, K3 ground-lift).
54 components, ERC 0 errors, netlist 0 errors. Per-stage files remain as the
documented, individually-simulated building blocks.

"""PM_K-1 audio chain - INTEGRATED board netlist (SKiDL).
Wires stages 1, 1b, 2, 3, 4 into one netlist with shared nets and DEDUPLICATED parts:
* the Stage-2 reconstruction filter and the Stage-3 summer share ONE OPA1612 dual
(U4: section A = filter, section B = summer) -- no parked half.
* the three relays (K1 select, K2 mute, K3 ground-lift) share ONE ULN2003 (U6).
This is the source of truth for the integrated audio netlist; the per-stage circuits/
files remain as the documented, individually-simulated building blocks.
Run INSIDE the EDA container:
cd hardware/eda && ./run.sh python3 ../eda/circuits/audio_chain.py
Outputs ERC + hardware/kicad/audio_chain.net.
All IC pinouts datasheet-verified (see the per-stage files for the citations):
