fix(update): bypass GitHub raw CDN cache for self-update#22
Conversation
The `crab update` command was reporting "Already up to date" even after a new version was merged, because raw.githubusercontent.com serves cached content (max-age=300). Add cache-busting via Cache-Control header and timestamp query param. Also validate the downloaded file contains a version string before replacing the binary.
