[BUG] Releases not gated behind changelog update. Doctor reports stale "Latest version".

What's Wrong?

This exact issue has been already reported (#6960, 7 upvotes). However, that issue has been automatically closed and locked due to inactivity. It was likely never addressed.

I have observed new updates being released before the changelog went live for both 2.1.152 and 2.1.153

As of right now, my claude code auto-updated to 2.1.153 (less than an hour ago). However, as of the time writing this comment:

• latest changelog entry is 2.1.152
• latest entry in https://code.claude.com/docs/en/changelog is 2.1.152
• latest release in https://github.com/anthropics/claude-code/releases is 2.1.152
• 'claude doctor' shows Latest version: 2.1.152

What Should Happen?

Proposed solution: Gate the latest release channel behind the GitHub release.

Steps to Reproduce

1. Enable auto-update in latest channel
2. Automatically check changelog on GitHub + 'claude doctor' when version updates
3. Observe that when claude updates, there is a delay before the changelog entry arrives and claude doctor reports the correct 'latest' version.

Is this a regression?
