fix(ci): fix dev-publish version stamp and platform sync (#1145)

Two bugs in the Dev Publish job:

1. node -p with escaped double-quotes broke on Node 22's eval mode
   (SyntaxError: Invalid or unexpected token). Switched to node -e
   with process.stdout.write and unescaped inner quotes.

2. version-stamp updated root package.json but not platform packages.
   When npm publish triggered prepublishOnly, sync-platform-versions
   dirtied 5 platform package.json files and git diff --exit-code
   failed. Added sync-platform-versions to the stamp step so
   prepublishOnly finds everything already in sync.
