Unsupported OS for upgrade

Error message

Unsupported OS for upgrade

What it means

Target-detection guard in the upgrade path: the binary was built for an OS other than linux, macOS, or windows (cfg!(target_os) matched none), so no release asset naming scheme exists for it. The platform itself is unsupported by self-upgrade, not a runtime failure.

Solutions

1. Upgrade manually: download the release for your platform from the GitHub releases page
2. Reinstall via the original installation method (npm, cargo install, package manager)

When it happens
