// bridgeStub implements plugin.PluginBridge over bridge.* capability calls.

// The bridge shares in-process Go values today; across sandboxes only the
// registration/lookup *surface* serializes — the service value itself cannot
// cross. RegisterService therefore forwards only plugin/service names (the
// value is dropped), and GetService returns nil (availability is checked but a
// typed value cannot be reconstructed guest-side). Typed cross-plugin
// invocation is an open ABI item (core/docs/wasm-abi.md).
