Add power-margin, PG-to-EN sequencing, and DNP enable checks.

Browse Source 
Compare only specified IQ plus I_load to Iout_max and series-R drop, flag sequencing only when power_sequence is in specs, and treat DNP as a fitted-variant graph so a missing enable pull is ERROR only when the BOM actually marks DNP.

What's new in Pinscope.
## 2.15.0 — 2026-09-10 — Power margin, sequencing, DNP enable
Schema checks now compare regulator load to Iout_max, look at PG→EN when a sequence is declared, and treat DNP as a fitted-variant graph.
- [New] `PS-PWR-001` when specified IQ+I_load exceeds Iout_max, or an explicit series R/ferrite DCR drops >5% of the rail. Missing IQ and PCB traces are not guessed.
- [New] `PS-SEQ-001` WARNING if `power_sequence` is in IC specs and upstream PG does not net to downstream EN.
- [New] BOM `DNP`/`Fitted`/`Variant` on `bom_fields`. Fitted enable with only a DNP pull is `PS-DNP-001` ERROR; no DNP column skips the check.
## 2.14.0 — 2026-09-10 — Filtri e termico schema
Deterministic checks now match RC/LC/π/T filters and estimate LDO/resistor dissipation without inventing missing numbers.
