Add PCB intra-pair skew only when the datasheet gives millimetres.

PS-SI-001 and decoupling skip without a numeric layout_rule. Tests use simple_project nets, not invented USBPHY boards.

What's new in Pinscope.
## 2.21.0 — 2026-09-10 — Layout SI skew (datasheet mm only)
Intra-pair skew is measured on the PCB only when `layout_rules` `length_match` has a number. 3W, creepage, and CPWG are not guessed.
- [New] `PS-SI-001` ERROR when a named pair (_DP/_DM, _P/_N) exceeds that millimetre. No mm in the datasheet → skip.
## 2.20.0 — 2026-09-10 — Placement vs datasheet (PCB)
Decoupling distance is measured on the `.kicad_pcb` against `layout_rules`. No board → no `PS-PLC-001`. A null millimetre uses the declared 3 mm default as WARNING.
Decoupling distance is measured on the `.kicad_pcb` against `layout_rules`. No board → no `PS-PLC-001`. A null millimetre skips — no 3 mm default.
- [New] `PS-PLC-001` when a decoupling cap is farther than `max_distance_mm` (ERROR) or the 3 mm default (WARNING). Empty `layout_rules` and missing caps skip.
- [New] `PS-PLC-001` when a decoupling cap is farther than datasheet `max_distance_mm`. Empty `layout_rules` and missing caps skip.
## 2.19.0 — 2026-09-10 — Finding review and ECO
