c2e1214fd1Port the KiCad symbol/footprint brace-scanner parsers + a combined extractor into web/backend/src/extract/; ensure-example-libs blobless/sparse-clones a curated KiCad 10.0.3 slice and extracts to a gitignored .libs/ on dev/start, so a bare GPL clone has libraries with no closed repo present. libsConfig() defaults LIBS_DIR to ./.libs. vite honors STANDALONE_PORT (strictPort) so a second editor can run on :3049 alongside the closed stack.
