bird update

bird update [flags]

Download and install the latest bird CLI release.

Fetches the latest version, verifies the SHA256 checksum, and atomically replaces the running binary. --check reports whether a newer version exists without installing anything. Set BIRD_CDN_BASE to point at a different artifact host.

A one-line notice on stderr announces a newer version, at most once a day. Set BIRD_NO_UPDATE_CHECK=1 to silence it and skip the version probe entirely.
