Restrict the marker predicate so non-marker comments are not counted.

The predicate accepts any line that starts with // and whose remainder contains / and no whitespace. A line such as // https://example.com/docs passes it. The line is counted in regionCount, and its text is scanned for node_modules/<package>/.

regionCount is documented as the signal that separates a clean bundle from a changed marker format. Counting non-marker comments weakens that signal. If the marker format changes and the bundle contains such a comment, the totalRegions === 0 guard in scripts/build-desktop-artifact.ts does not fire, and the scan can pass. A comment containing node_modules/<external-package>/ also adds that package to inlined, which fails the build with InlinedExternalPackageError.

Narrow the predicate to the module-id shape that Rolldown emits. Add a test with a single-token, non-marker comment that contains a /, such as a URL. The current test only uses a prose line, and the space check already rejects that line.

Review comment at @scripts/lib/cli-external-packages.ts around lines 64 - 76:
Narrow the marker check around regionCount to accept only Rolldown’s emitted
module-ID shape, so URL comments or other non-marker comments are not counted or
scanned for packages. Add a test with a single-token comment containing a slash,
such as a URL, and verify it does not count as a marker.
