fix: address review — stale progress, cross-platform prepare, DEV log

- Clear progress after handleServerConnect in both auto-connect and
  DropZone paths (fixes frozen progress bar on StatusBar)
- Replace shell-based prepare script with Node scripts/prepare.cjs
  for Windows cmd.exe compatibility
- Gate LadybugDB load warning behind import.meta.env.DEV (consistent
  with finalizePipeline's silent catch)
- Remove misleading "parallel" comment (fetch is sequential after connect)
