use C_Small/R_Small

[LK]

Note

Low Risk
Symbol-only change for passives and import placement; netlist hashes shift but connectivity is unchanged.

Overview
Stdlib generic Resistor and Capacitor now use KiCad R_Small and C_Small instead of R / C, which changes schematic appearance and netlist output (release snapshots updated).

KiCad import promotion and # pcb:sch placement math now target Device:R_Small / Device:C_Small for bbox and axis compensation; related unit tests were adjusted accordingly.

Test sandbox: low-level run_git disables global/system git config and interactive credential prompts so fixture git stays hermetic in CI.

IPC-2581 HTML export: template/CSS include_str! constants were moved above the test module (no behavior change).

Cursor Bugbot has reviewed your changes and found 2 potential issues.

Bugbot Autofix prepared fixes for both issues found in the latest run.

• ✅ Fixed: US resistor symbol not updated to small variant
  • Updated stdlib/generics/Resistor.zen so the use_us_symbol branch now selects R_Small_US instead of R_US for symbol-size consistency.
• ✅ Fixed: Test fixtures reference stale Device:R target symbol key
  • Updated the resistor promotion fixtures in crates/pcb/src/import/generate.rs to use Device:R_Small/R_Small_0_1 so geometry lookup matches the new promoted target lib id.

US resistor symbol not updated to small variant

Medium Severity

The use_us_symbol branch still uses "R_US" instead of the small variant "R_Small_US" (which exists in KiCad's Device library). The non-US path was updated from "R" to "R_Small", but the US path was missed. This means users with use_us_symbol=True get a full-size symbol while everyone else gets a small one, creating an inconsistency.
