Replace the legacy Emscripten JS-exceptions model with native wasm-EH (legacy encoding) across the whole build, keeping Asyncify coroutines working via a from-source Binaryen --hoist-cpp-catches pre-pass. Net result: native-EH is the only build mode, the 3D viewer is on by default, and pcbnew shrinks substantially. Highlights: - Binaryen submodule everywhere + --hoist-cpp-catches integration in apply-asyncify; post-link Asyncify covers every app wasm (not just standalone test wasm). - Build deps (incl. OpenCASCADE without OCC_CONVERT_SIGNALS) and all KiCad apps with -fwasm-exceptions; emscripten_sleep added to the post-link asyncify-imports. - libcontext fiber entry wired under native exceptions; while-loop main loop + currData shim injected into all wx apps. - Native-EH collab apply fixed: DEBUG-define the embind TU + match all out-of-CMake C++ TUs' ABI flags to the core, fixing the vtable-layout skew / mis-dispatch. - 3D viewer enabled by default (real raytracer linked, not the stub). - Retire the EH-spike scaffolding; flip the asyncify-races ablation pins to shim-redundancy pins (native-EH stays clean with the legacy shims ablated). - Fix the asyncify-races quiescence check to not require Asyncify.currData==0: under the native-EH per-frame-yield top loop the main stack is asyncify-suspended every frame, so currData legitimately churns (a freed-but-not-yet-nulled buffer, not a leak). Refresh the pcbnew toolbar screenshot baseline for the new kicad. - CI: drop the obsolete binaryen_version input/env (the build uses the binaryen submodule fork's wasm-opt, not a version download); key the wasm-output cache on the binaryen submodule SHA instead. Bumps the wxwidgets + binaryen submodules to their squashed feature commits. Validated green: all 7 apps native-EH (real 3D in pcbnew); KiCad e2e 63/63 Firefox + Chromium (3D viewer renders); wx 336; coroutine 34/34 both engines; asyncify 7/7 both engines.
