feat: add bundle-host-test.cjs + smoke integration
- bundle-host-test.cjs: JS smoke-test for PluginBundleHost contract - 4 error boundary scenarios (missing frontend, JS throw, missing component, mount throw) - 5 real mount scenarios (bundle exec, DiagnosticsPanel mount, Settings mount, unmount, mount-throw catch) - Runs real platform-test bundle in vm.Sandbox with mock window/document - smoke-platform.sh: add bundle-host-test step - Fix: platform-test badgeRow div call (3rd arg was ignored)

/**
|
||||||
|
* bundle-host-test.cjs — Headless smoke-test for PluginBundleHost contract.
|
||||||
|
*
|
||||||
|
* Tests:
|
||||||
|
* 1. Error boundary: missing frontend entry (no bundle)
|
||||||
|
* 2. Error boundary: bundle JS throws during execution
|
||||||
|
* 3. Error boundary: component id not found in bundle
|
||||||
|
* 4. Error boundary: component mount throws at runtime
|
||||||
|
* 5. Real mount: bundle executes and registers components
|
||||||
|
* 6. Real mount: DiagnosticsPanel writes expected text to container
|
||||||
|
* 7. Real mount: PlatformTestSettings writes expected text to container
|
||||||
|
* 8. Real mount: cleanup (unmount) empties the container
|
||||||
|
* 9. Real mount: component mount throw is catchable
|
||||||
|
*
|
||||||
|
* Runs the real platform-test frontend/dist/index.js in a vm.Sandbox
|
||||||
|
* with a minimal window/document mock.
