- Replace /MIN (hidden window) with normal windows so errors are visible
- Redirect stderr to logs/*.log for post-mortem
- Extract killport/wait_health/wait_port into callable helpers
- Use !N! (delayed expansion) for retry counters
- stop.bat now shows which PIDs it kills with port labels
- Remove nested-quote issue by cd'ing before npm start
Each service wait loop now fails after 30 retries (~60s) instead of
spinning forever when a port is occupied by a stuck process.
Also added cleanup label that kills partially-started services on failure.
cmd /k "cd /d "%~dp0" && ..." breaks because inner quotes around
%~dp0 close the outer quoted string prematurely when the path
contains spaces (D:\Idea Project\...). Fix: remove outer quotes,
escape && as ^&^& so it passes through to the new cmd instance.
