Single workflow_dispatch (version, dry_run) that bumps versions, regenerates
CHANGELOG via git-cliff, rebuilds site CSS, builds all targets, creates the
GitHub release, updates the Homebrew tap and publishes Chocolatey.
- dist/release/bump_version.sh: version replacer across all tracked locations (+tests)
- .github/workflows/release.yml: prepare -> build matrix -> homebrew/release -> choco
- retire build-artifacts.yml (merged into release.yml)
- Linux builds via cargo-zigbuild (old glibc) for broad compatibility
