- Add ccache to Docker image for compiled object caching - Change build defaults: incremental by default, skip deps by default - Add new flags: --full, --clean-kicad, --build-deps - Skip wxWidgets configure if already configured (check Makefile timestamps) - Remove unused source hash stamp functions (make handles dependencies) - Update build.md with new build system documentation Performance improvements: - Single file change: 7:35 → 1:34 (4.8x faster) - No-change rebuild: 7:35 → 1:31 (5x faster) - Asyncify post-processing (~1 min) is now the bottleneck 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
