fix: 5 critical bugs from Codex review

1. Windows: change "node npm.cmd" to "call npm.cmd" (npm.cmd is a
   batch wrapper, not a JS file — can't run with node.exe)
2. Build: use pnpm instead of npm (upstream build script calls pnpm
   subcommands that fail without it); add set -eo pipefail
3. Build: fail explicitly when dist/ not generated instead of || true
4. Run scripts: separate first-time onboard from normal startup
   (was running onboard every time, blocking normal launch)
5. Windows .bat: fix findstr patterns for .env dedup with /r flag
