Introduces the `ReflectAndRetryModelPlugin`, which provides error recovery
for model failures (such as malformed function calls). When a configured model
error occurs, the plugin intercepts it, provides reflection guidance to
the model via a reserved tool call, and retries the operation.
Key features:
- Configurable max retries for model errors.
- Customizable list of FinishReasons to treat as errors.
- Support for both invocation-level and global-level tracking scopes.
- Interception of direct calls to the reserved retry tool to prevent misuse.
