KiCad footprint subset and adapted numeric geometry

Modified: extracted pad, body and courtyard coordinates for seven footprints into source/footprints.mjs; rendering is simplified and omits native text, models and some outline details. The adapted footprint data remains under the same library license.


Open-source export integration (v0.5)
Upstream modules are bundled unchanged; the PCBA Partner adapter translates project geometry and nets only.
