fix(build): fix runtime bugs in build scripts

- Fix plugin ordering in esbuild.cli.build.mjs: envVarReplacementPlugin
  was running before unicodeTransformPlugin despite comment saying after.
  Swap order so unicode transform runs first.
- Fix watch mode crash in build.mjs: watchResult?.code can be undefined
  when spawn returns null. Add null check and fallback ?? 1.
- Fix allSettled pattern in build.mjs post-processing: Promise.all
  swallows individual rejections. Switch to Promise.allSettled with
  proper rejection detection.
- Fix allSettled pattern in download-assets.mjs: same Promise.all issue,
  now uses Promise.allSettled with r.status === 'rejected' check.
- Fix allSettled pattern in download-iocraft-binaries.mjs: same fix.
- Fix createBuildRunner in esbuild-shared.mjs: catch block never
  rethrew, so callers using allSettled could not detect failures.
- Remove dead script entries from cli/package.json (e2e:smol,
  build:sea:internal:bootstrap, publish:sea).
