+Tighten the pre-1.0 public API surface by keeping low-level core helpers out of the main `@execbox/core` entrypoint, removing unsupported QuickJS runner subpath exports, and keeping runner-side remote endpoint types with `@execbox/quickjs/remote-endpoint`.

 ## Advanced Imports
 
-- `@execbox/quickjs/runner` exports the reusable QuickJS runner
-- `@execbox/quickjs/runner/protocol-endpoint` exports the low-level QuickJS protocol loop used by worker-hosted integrations
 - `@execbox/quickjs/remote-endpoint` adapts the QuickJS protocol loop to `@execbox/remote` runner ports
