Promote CLI from 1.0.0-alpha.42 to stable 1.0.0 so `npm i -g claudemesh-cli` installs the current release without needing the @alpha dist-tag. Both dist-tags now point at 1.0.0 — `@alpha` kept as an alias for continuity so existing docs, install scripts, and scheduled upgrade commands keep working. upgrade + doctor commands updated to prefer the `latest` dist-tag (falling back to `alpha`) and to suggest `npm i -g claudemesh-cli` without the @alpha suffix.
