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

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]
