pcbjam/wasm/bindings/kicad_editor_embind.cpp

/*
 * Embind dispatcher for the merged kicad_editor WASM image (editor-unification Part 2).
 *
 * The pcbnew and eeschema binding TUs each implement the collab bridge for their own
 * frame and, standalone, register the SAME JS-facing names. In the merged image both
 * TUs are compiled with -DKICAD_MERGED_EMBIND, which
 *   - compiles out their duplicate frame-agnostic definitions (kicadOpenFile,
 *     extern "C" kicadCollabOnSave) — the single definitions live HERE, and
 *   - compiles out their shared-name EMSCRIPTEN_BINDINGS registrations — registered
 *     once HERE, dispatching to the renamed per-editor entries (pcbCollab… and
 *     schCollab…) on whichever editor frame is live. Per-editor unique names
 *     (kicadSaveBoard, kicadSaveSchematic, kicadCollabTestItemBlob, Board_…) keep
 *     flowing from the per-editor blocks unchanged.
 *
 * With the one-frame-per-page-load model exactly one of pcbEditorActive() /
 * schEditorActive() is true — the same dynamic_cast probe every per-editor entry
 * already starts with. JS-facing names and signatures are IDENTICAL to the standalone
 * bundles, so the web app and tests need no per-bundle API differences.
 *
 * Deliberately header-light: no pcbnew/eeschema headers (avoids mixing both include
 * roots in one TU); only the generic KIWAY_PLAYER surface + the extern declarations.
