v1.12.5
Add `copilot-api update` self-update subcommand Lets users upgrade a release binary in place: queries the latest GitHub release, compares against the running version, and atomically swaps the running executable with the platform asset via the self-replace crate. Defaults to a confirmation prompt; --yes skips it and --check dry-runs. Reuses the shared rustls HTTP client and asset names from release.yml.
