fix: add --external @ast-grep/napi to CLI build command (#350)

The CLI build was missing --external @ast-grep/napi flag, causing the bundler
to inline absolute paths from the CI environment (/home/runner/work/...).
This made the doctor check for @ast-grep/napi always fail on user machines.

Fixes #344
