Build improvements: - Change -O0 to -O1 to fix "local count too large" asyncify error - Add wasm-emscripten-finalize to host (Docker OOMs on large WASM) - Use -gseparate-dwarf for smaller main binary with debug info - Build native protoc for code generation - Add more functions to asyncify removelist Runtime fixes: - Add inject-dyncall-shims.sh to fix "dynCall_* is not defined" in Emscripten 4.x - Update wxwidgets with browserInfo.name fix New stubs and bindings: - Add Embind bindings for JavaScript interop - Add stubs for scripting, API plugin, PCB frame, navlib 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Build KiCad WASM inside Docker container, then apply asyncify on host
|
|
#
|
|
# The build is split into two phases:
|
|
# 1. Docker: Compile KiCad to WASM (without asyncify)
|
|
# 2. Host: Apply asyncify transformation (uses Binaryen v121)
|
|
#
|
|
# Binaryen is downloaded automatically - no prerequisites needed.
