Add hammer update self-update command#8
Merged
Conversation
Add an `update` subcommand that replaces the running binary with the latest GitHub release. It resolves the target release via the GitHub API, downloads the platform archive (tar.gz, or zip on Windows), verifies it against SHA256SUMS, and atomically swaps the binary in place (with a cross-filesystem copy fallback and the Windows rename-aside path). Reuses the install.sh mirror ladder (auto/github/ghproxy/custom proxy via -mirror or HAMMER_INSTALL_MIRROR) and HAMMER_REPO for forks. Flags: -check, -version, -y/-yes. Semver-aware so it won't downgrade or reinstall the same version; a dev build always upgrades to a real release. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
