fix(bootstrap): load Intl polyfill before logger to prevent smol build failure

Add Intl polyfill import at the top of bootstrap files before any other
imports that use Intl APIs. This fixes the "Intl is not defined" error
in smol Node.js builds (ICU-disabled) where logger's stringWidth function
uses Intl.Segmenter.

Changes:
- Copy intl-stub polyfill from cli/src/polyfills to bootstrap package
- Import polyfill as first statement in bootstrap-npm.mts and bootstrap-smol.mts
- Rebuild bootstrap package to embed polyfill before Intl.Segmenter usage

The polyfill checks if globalThis.Intl exists and only installs stubs if
missing, making it safe for both ICU-enabled and ICU-disabled builds.
