- Add build.md documentation for the WASM build system - Default to debug builds with -gsource-map for WASM debugging - Add --release flag to disable debug symbols - Add --clean flag for full rebuild (deps + wxWidgets + KiCad) - Add -j N flag for parallel compilation (default: 1 for sequential) - 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) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
