feat(libs): standalone .lib→.kicad_sym wasm converter (sym_convert)

Browse source 
Headless node-WASM CLI that converts legacy symbol libraries to .kicad_sym via
SCH_IO_MGR::ConvertLibrary. Adds wasm/cli/sym_convert_main.cpp + sym_convert_pre.js
(in-memory localStorage + wxConfig JS-hook shim), registers sym_convert as a
docker/build.sh app (own kicad-sym_convert tree, real wasm-opt/finalize in-container,
skip host postprocess), and bumps the kicad pointer for the matching target.
