Replace timestamp-based rsync + touch with checksum-based sync: - Use --checksum to only transfer files with actual content changes - Remove touch mechanism that caused all files to appear "newer" - Exclude .git, logs, .idea, node_modules from sync The old approach created a perpetual timestamp mismatch: 1. rsync -a preserved host timestamps 2. touch set container timestamps 3. Next build saw mismatch → transferred everything → touched again With --checksum mode: - Changed files: transferred with current time → rebuilt (correct) - Unchanged files: not transferred → keep timestamp → no rebuild (correct) Tested scenarios: - Consecutive builds: ~2 min (cached) vs ~6+ min (was full rebuild) - Modified wxWidgets file: only that file recompiled - Modified KiCad file: only that file recompiled 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
