What's Wrong?

When trying to update claude in a terminal running outside of VS Code, and with the Claude Code VS Code native extension enabled (not active, just enabled) I most often (but not always?) see the following error if I try to run claude update.

➜  claude update
Current version: 2.0.58
Checking for updates...
Another process is currently updating Claude. Please try again in a moment.

Then, when this happens (not always), if I do nothing but disable the Claude Code VS Code extension and return to the external terminal to run claude update again I see success:

➜  claude update
Current version: 2.0.58
Checking for updates...
Claude Code is up to date (2.0.58)

It is not always predictable, and seems possibly related to some kind of stale update lock that the extension is managing poorly if I had to guess.

What Should Happen?

Running claude update in a terminal, even with Claude Code VS Code extension installed/running/enabled, should allow the update of the claude code terminal native command.
