I opened #672—thanks for the fix!

I noticed the new __...__ handling misparses foo__https://example.com/__、英語版. The __ after foo is intraword, so it shouldn't open strong emphasis, but the PR treats it as a delimiter and drops the trailing __ from the link target.

Could you take a look?

Fixed the reported CJK autolink case. The intraword foo__ remains literal, the URL target keeps its trailing __, and CJK punctuation and following text stay outside the link. The scanner also preserves URL text inside real inline link labels, including empty destinations with titles.

Validation: pnpm test (1,953 tests) and pnpm build:packages passed. Thanks for the report.
