Add a Release workflow that runs nightly (6 AM UTC) and supports manual
dispatch. It computes the next patch version from the latest v* semver
tag, builds CLI binaries for all platforms (Linux amd64/arm64, macOS
aarch64), creates a git tag, and publishes a GitHub Release.
Also adds a next-version subcommand to release.py to centralize version
computation, and updates install.sh to default to the latest GitHub
release instead of devel.
