Package and distribute Sandbox Runtime CLI and WordPress plugin

[chubes4]

Gap

Sandbox Runtime is prototype-shaped. Consumers need reliable install/update paths for the CLI and WordPress plugin.

Goal

Define packaging and release artifacts for the npm CLI and WordPress integration plugin.

Acceptance direction

• Publishable npm package for @chubes4/sandbox-runtime-cli or final package name.
• Buildable WordPress plugin zip artifact from packages/wordpress-plugin.
• Versioning policy across CLI/core/playground/plugin packages.
• Install docs for self-hosted, Studio/local, and hosted control-plane environments.
• Runtime discovery for CLI binary path from the plugin.
• Release checklist with smoke tests.

Notes

Hosted platforms may provide Sandbox Runtime as managed infrastructure, but local/self-hosted consumers need explicit packaging.
