Gate SI layout_rules to the quoted bus, not EN RC onto USB.

Browse Source 
PE-SI-009 no longer treats ESP32 CHIP_PU/EN RC as a USB series R.
USB without a library Z number stays PE-SI-010 measurement-only.
Pintable skill 1.13.0 requires net_class on SI kinds (usb2/usb3/MDI/RGMII/DDR3).

What's new in Periscope.
## 2.37.0 — 2026-09-20 — SI bus gate (EN RC ≠ USB series R)
Datasheet SI facts apply only to the bus in the quote. ESP32 EN RC 10 kΩ / 1 µF is not a USB D+/D− series resistor. USB without a library Z number stays measurement-only (88 Ω), not a 90 Ω FAIL. Coverage: PHY+RJ45 MDI, MAC–PHY RGMII/SGMII, DDR3, USB-C SuperSpeed.
- [Fixed] `PE-SI-009` (and other SI kinds) require `net_class` / quote bus match; strap/EN RC is skipped.
- [Changed] `bus_class`: `usb2` / `usb3` / `eth_mdi` / `rgmii` / `sgmii` / `ddr3_*`.
- [Changed] `PE-SI-010` is per bus with no impedance FACT (not silenced by an unrelated SI kind).
- [Changed] Pintable skill `1.13.0`: SI `net_class` required; EN/CHIP_PU RC is not `series_resistor`.
## 2.36.0 — 2026-09-20 — Fase A: operator identity + PinScope fence
This instance is operated by Michele Bigi. Faradworks, Inc. is not the operator. PinScope identifiers are dual-read only. PCB BOM/SPOF/EMI/θJA slices from 2.35.0 stay on this branch.
