Sample external plugin collection

Automax ships a small external plugin example under examples/external-plugins/. It validates the external plugin SDK packaging workflow without requiring a private plugin repository.

automax plugins check examples/external-plugins/company/plugins
automax plugins package examples/external-plugins/company/plugins --output dist/company-demo-plugins.zip --force
automax plugins verify-package dist/company-demo-plugins.zip
automax plugins index dist/company-demo-plugins.zip --output dist/automax-plugins-index.json
automax plugins install-package dist/company-demo-plugins.zip --dest-dir .automax/plugins --force

The sample plugin exports company.demo.hello and is intentionally deterministic so it can be used in release and packaging smoke checks.
