fix: properly bundle @InQuirer modules as external dependencies

The @inquirer/input, @inquirer/password, and @inquirer/search packages
were not being bundled into dist/external, causing socket-cli's build to
fail when trying to resolve these modules. This fix adds these packages
to the bundling configuration in build-externals.mjs so they are properly
bundled with esbuild instead of being left as stub re-exports.

This ensures socket-cli can properly resolve @InQuirer dependencies when
importing from @socketsecurity/lib, fixing the build chain dependency
resolution issue.
