fix(wasm): Fix Asyncify modal errors with global lock mechanism

Update wxwidgets submodule with fix for consecutive modal dialog crashes.
The fix prevents overlapping Asyncify operations that caused "indirect call
to null" and "func is not a function" errors when a second modal was
triggered immediately after the first one completed.

Also includes:
- docs: Clarify build script order and descriptions in CLAUDE.md
- refactor(test): Remove debug logging from wizard test
