Verify review quotes against datasheet PDF text and extract ESD Vrwm/polarity.

ERROR/WARNING without a real citation are demoted to Unverified so invented topologies like a unidirectional TPD2E007 clamp cannot ship as ERROR.

+- Working / reverse working voltage **Vrwm** (or V_RWM / "operating voltage") as a **signed** min/max in volts — e.g. bidirectional ±13 V is `min: -13`, `max: 13`, `unit: "V"`.
+- One extra row whose `parameter` states polarity/topology as printed (`bidirectional`, `unidirectional`, `back-to-back`), `unit: "—"`, min/max omitted. Do **not** infer unidirectional from "IO" pins that list GND as the reference pin.
