- 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

Build the 3D viewer code for WASM instead of stubbing it out.
This is simpler to maintain than complex header stubs.
Changes:
- Enable KICAD_BUILD_3D_VIEWER_WASM=ON in build script
- Remove -gsource-map to avoid OOM in wasm-emscripten-finalize
- Add OpenGL stubs for fixed-function pipeline (WebGL ES 2.0 only)
- Add GLU stub for gluErrorString
- Add NNG stub for IPC API (sockets don't work in WASM)
- Add PCBnew scripting stub
- Expand curl and libgit2 stubs
The 3D viewer code compiles but won't render at runtime since
OpenGL GAL is disabled and Cairo GAL is used instead.

The KiCad WASM build was freezing during initialization due to a pthread
deadlock. When hardware_concurrency() > PTHREAD_POOL_SIZE, new Web Worker
creation requires the event loop, but the main thread busy-waits blocking it.
Changes:
- Use navigator.hardwareConcurrency for PTHREAD_POOL_SIZE in KiCad build
- Add threadpool test to reproduce and verify the fix
- Add single-target build support to build-wasm-test.sh
- Default docker/build.sh to -j 10 for faster builds

- Increase thread pool size from 4 to 8 with STRICT=0 to prevent
"thread pool exhausted" errors when KiCad creates worker threads
- Add thisProgram='/usr/bin/pcbnew' to provide absolute path for
argv[0], fixing "No meaningful argv[0]" DEBUG check in KiCad

Build script changes:
- Use embuilder to build zlib port (works in Docker and on host)
- Use em-config CACHE for portable sysroot path
- Fix symlink creation to avoid "same file" errors on re-runs
wxWidgets submodule update:
- Fix toplevel window sizing to return 1280x720 instead of 20x20
- Handle default size like GTK/MSW ports before passing to base class

- Add source hashing to stamp system (functions.sh) for detecting
when dependencies need rebuild based on source file changes
- Update build-pcbnew.sh to use source stamps for wxWidgets
- Add global-setup.ts to clean logs before test runs
- Add maximize_test standalone test to verify wxFrame::Maximize()
works correctly in WASM (it does - window is 1280x720)
- Update Makefile.wasm with maximize test build rules
The maximize_test proves wxWidgets display detection works fine.
KiCad's 20x20 window bug is KiCad-specific, not a wxWidgets issue.

- Update Docker memory limit to 32GB
- Propagate DEBUG_BUILD and JOBS to all dependency scripts
Build modes:
- ./docker/build.sh --clean -j8 (full rebuild, parallel)
- ./docker/build.sh (rebuild KiCad only)
- ./docker/build.sh --no-clean (incremental)

The wxGrid test was crashing with "memory access out of bounds" due to
an initialization order bug in grid_test.cpp: during CreateGrid(), wxGrid
fires cell selection events which triggered the OnGridCellSelect handler
that called m_log->AppendText() before m_log was initialized.
Fix: Add null check in LogEvent() to guard against events firing before
m_log is created.
Also adds --debug flag to build-wasm-test.sh for debugging WASM crashes:
- Builds with DWARF symbols (-g) and source maps (-gsource-map)
- No optimization (-O0) preserves debugging context
- Stack traces show actual function names instead of wasm-function[N]
