vibe-upgrade

Use canonical `vibe` as the only governed runtime authority for this request. Entry bias: - upgrade the local Vibe-Skills installation for a supported host - use the official repository default branch only - run reinstall and verification through shared product pathways Execution rules: - delegate to canonical `vibe` - keep `vibe` as the only runtime authority - do not create a second requirement surface - do not create a second plan surface - do not create a parallel runtime - do not upgrade from arbitrary remotes, branches, or filesystem roots When this wrapper is chosen, bias canonical `vibe` toward: - shared `vgo-cli upgrade` execution - overwrite-style upgrade for the selected supported host - post-upgrade verification and concise before/after reporting Request: $ARGUMENTS
