Root cause: Windows batch files written with LF endings caused cmd.exe to misparse labels and Chinese characters, producing garbled "not a command" errors. The Python launcher avoids encoding issues entirely. - start.py: reliable cross-platform launcher (kill ports, start 3 services, wait for health, print status) - start.bat / start_all.bat: minimal 4-line ASCII wrappers - stop.bat: inline Python for port-based process killing
