fs: fix glob early return skipping sibling entries

[semimikoh]

Summary

• Remove cache.seen check from children iteration loop in #addSubpatterns (sync) and #iterateSubpatterns (async)
• The return inside the loop exits the entire method, skipping all remaining siblings
• The cache.add at the top of each method already prevents reprocessing and infinite recursion

Fixes: #62897

Test plan

• Run test-fs-glob.mjs multiple times to verify flakiness is resolved
• Verify the reproduction script from the issue passes consistently

Hi @semimikoh, are you still working on this? It looks like CI hasn't passed and there's been no activity for a while. If you don't have time to continue, I'd be happy to take this over and finish the fix (with credit to your work here). Thanks!

[semimikoh]

@trivikr Sure, feel free to take it over and continue the work. Thanks!

[webdevelopersrinu]

Thanks @semimikoh Just to confirm I think you meant me (@webdevelopersrinu), as I'm the one who asked above 🙂. I'll take this over, keep your work credited with Co-authored-by, and open a PR with the fix + regression test + green CI.
