Viktor Vaczi c1ef489cfa feat(wasm-eh): migrate the WASM build to native wasm exceptions (+ 3D viewer default-on)
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.

name: CI full build + e2e (Ubicloud)
# Main/PR gate: build all 6 KiCad WASM tools + run the wxWidgets + KiCad e2e
# suites on a Ubicloud runner. The actual recipe lives in the reusable
# wasm-build.yml (the SINGLE build definition) — this is just the main/PR caller,
# pinned to -O1 for fast feedback. The tag release (release.yml) calls the same
# recipe at -O2 (the shipped demo opt level) and then publishes, so the build can
# never diverge from what ships.
#
# Routine edits under scripts/ do NOT bust the WASM output cache — only the subset
# in scripts/deploy/wasm-cache-hash.mjs does. For inputs the sc-hash can't see
# (base-image / apt drift, a bad cache) bump .ci-cache-epoch; for a one-off
# rebuild put [no-cache] or [rebuild-wasm] in the commit message / PR title.
