📝 WalkthroughWalkthroughAdds a StandaloneAopContextHook to pre-create context-scoped AOP advice in standalone mode, wires it into Runner lifecycle for registration and cleanup, exposes the hook via the public index, and includes fixtures and tests demonstrating SingletonProto + ContextProto advice behavior.

Code Review
This pull request introduces a fix for an issue where ContextProto advices were not being created in subsequent requests when used by a SingletonProto in standalone mode. The fix introduces StandaloneAopContextHook, which proactively discovers all context-scoped advices during initialization and ensures they are created with each new context. The implementation is accompanied by a clear test case that reproduces the bug and verifies the fix.
My review focuses on improving the API surface hygiene. I've suggested making a couple of helper interfaces internal to the module as they don't seem to be intended for public consumption.
Overall, this is a well-executed fix for a tricky AOP-related issue.

The interfaces EggPrototypeWithClazz and ProtoToCreate appear to be internal implementation details for StandaloneAopContextHook. Since index.ts uses export * from './src/StandaloneAopContextHook', these interfaces are exposed as part of the package's public API. To maintain a clean public API and signal that these are for internal use, it's better to define them without exporting.
| export interface EggPrototypeWithClazz extends EggPrototype { | |
| clazz?: EggProtoImplClass; | |
| } | |
| export interface ProtoToCreate { | |
| name: string; | |
| proto: EggPrototype; | |

In `@standalone/standalone/test/fixtures/singleton-aop-module/main.ts`:
- Around line 15-19: Replace the private-field access this.graph['initialized']
with a public accessor on Graph (e.g., add a method isInitialized(): boolean)
and call that here (if (!this.graph.isInitialized())). Update the Graph class to
expose the new isInitialized() method and ensure existing mutations still set
the private initialized flag internally; keep the rest of the flow (calling
EggContainerFactory.getOrCreateEggObjectFromClazz(QueryNode), casting to
QueryNode, and calling
this.graph.setBoundExecute(queryNode.run.bind(queryNode))) unchanged.

Accessing a private Graph field through bracket notation violates TypeScript's access control.
this.graph['initialized'] accesses a private field and will be rejected by TypeScript even in bracket notation—both dot and bracket access are type-checked for private modifiers in strict mode. Expose a public accessor method on Graph and use that instead.
Proposed fix in this file
- if (!this.graph['initialized']) {
+ if (!this.graph.isInitialized()) {
// Get QueryNode only during graph initialization (first request)
const queryNodeObj = await EggContainerFactory.getOrCreateEggObjectFromClazz(QueryNode);
const queryNode = queryNodeObj.obj as QueryNode;
this.graph.setBoundExecute(queryNode.run.bind(queryNode));
}Corresponding update in Tool.ts

private boundExecute: ((input: string) => Promise<string>) | null = null;
private initialized = false;
