Documentation synchronization verification - no changes needed

[Copilot]

Automated workflow created this issue to check for unsynchronized documentation fixes across English, Japanese, and Korean versions. Investigation confirms all recent fixes are already applied.

Verified Synchronization

All documentation changes since July 2025 have been correctly synchronized:

• PR Update streaminghub/getting-started.md #990 (Dec 4): StreamingHub LeaveAsync() fix → Applied to JA/KO in Sync PR #990 fix to Japanese and Korean documentation #995
• PR Update extensibility.md #959-960 (Jul): Filter typo and method fixes → Applied to JA/KO in Apply fixes from PR #960 and #959 to Japanese and Korean documentation #962
• PR Update json-transcoding.md #966 (Jul): JSON transcoding troubleshooting → Applied to EN/JA in Apply PR #966 fixes to English and Japanese JSON transcoding documentation #968
• PR feat: add overload IncludeMagicOnionXmlComments  #978 (Sep): Swagger overload docs → Applied to all languages

Content spot-checks confirm:

// streaminghub/getting-started.md - All languages use:
room.All.OnLeave(userName);  // Not ConnectionId.toString()

// filter/extensibility.md - All languages use:
class SampleFilterAttribute : ... Attribute  // Not Attrubute

Context

This issue was created by the docs-translation.yaml workflow (added in #1001) during its first manual trigger on Dec 9. The workflow correctly creates issues for manual verification. In this instance, verification confirms synchronization is complete.

No documentation changes required.
