Auto-Update feature in Kane CLI

[anubhavsinghmaar]

What would you like and why?

Kane CLI has no built-in way to update itself.

On v0.7.1:

$ kane-cli --update
error: unknown option '--update'

No update subcommand either — upgrading means npm install -g @testmuai/kane-cli@latest
or brew upgrade kane-cli by hand.

Worth noting the CLI already knows when it is behind:

$ cat ~/.testmuai/kaneai/version-check.json
{"latest":"0.7.1","checkedAt":1786292556785}
