pcbjam/wasm/cli/kicad_tools_main.cpp

/*
 * kicad_tools — merged headless KiCad CLI, built as ONE WebAssembly module
 * linking both dieted kifaces (pcbjam-mcp 0001 tier 3a).
 *
 * Thin dispatcher over the two per-app entry points (compiled into this image
 * with KICAD_TOOLS_COMBINED, which strips their standalone main()s):
 *
 *   pcbnew side   (pcb_convert_main.cpp):
 *     kicad_tools --drc [--json] [--strict] <file.kicad_pcb> [<out>]
 *     kicad_tools --gerbers <file.kicad_pcb> [<outdir>]
 *     kicad_tools --drill <file.kicad_pcb> [<outdir>]
 *     kicad_tools --plot-board [--pdf] [--layers <a,b,...>] <file.kicad_pcb> [<out>]
 *
 *   eeschema side (sym_convert_main.cpp) — everything else:
 *     kicad_tools --convert-lib <input.lib> <output.kicad_sym>
 *     kicad_tools --lint [--strict] <file> [<file>...]
 *                       (.kicad_pcb files get a FULL parse here — the pcbnew
 *                       parser is linked; the lint driver calls back into
 *                       pcbToolsLintBoard on the pcb side)
 *     kicad_tools --erc [--json] [--strict] <file.kicad_sch> [<out>]
 *     kicad_tools --netlist [--xml] <file.kicad_sch> [<out>]
 *     kicad_tools --bom <file.kicad_sch> [<out>]
 *     kicad_tools --plot [--pdf] <file.kicad_sch> [<out>]
 *
 * Each side brings up its own minimal PGM runtime on first use; dispatch is
 * exclusive per process, so the two runtimes never coexist.
