Add DC-bias C_eff stima to derating and INFO when bulk C has no HF ceramic.

Browse Source 
Keep both as labelled estimates: no Murata lot curve and no invented Z(f) target without f_sw.

What's new in Pinscope.
## 2.13.0 — 2026-09-10 — DC-bias C_eff stima
The derating table now shows an effective capacitance under DC bias for C0G/X7R/X5R ceramics. It is labelled *stima* — not a vendor lot curve.
- [New] `C_eff` column from an empirical V/Vrated table. Tantalum/electrolytic and unknown dielectrics are left blank.
- [Improved] C0G/NP0 stays at nominal C; X7R at 50% of rated V is about 70% of C.
- [New] Bulk C without a ~100 nF ceramic is `PS-ESR-001` INFO (no invented Z(f) target).
## 2.12.0 — 2026-09-10 — Pull-up sizing and LDO Cout
Deterministic schema checks now size I2C pull-ups, flag NRST pull-downs, and look at LDO VOUT capacitance — still WARNING, never a invented datasheet µF ERROR.
