feat(cliproxy): add unregisterOpenAICompatExecutor and sync runtime configuration

- Implemented `unregisterOpenAICompatExecutor` to remove OpenAI-compatible executors dynamically.
- Updated `ensureExecutorsForAuth` to unregister incompatible executors while handling plugin candidates.
- Adjusted runtime configuration logic to ensure proper synchronization during updates with `syncPluginModelRuntime`.
