chore(npm): mark hanzo-ai (raycast) + hanzo-ide (vscode) npm-private

npm rejects the unscoped 'hanzo-ai' name (too similar to existing 'hanzoai'), and
both publish to their OWN stores (Raycast Store / VS Marketplace) via dedicated
jobs — they don't belong on npm. Setting private so pnpm -r publish skips them.
