chore: update @librechat/agents dependency to version 3.0.71 and enhance agent tool loading logic

- Updated the @librechat/agents package to version 3.0.71 across multiple files.
- Added support for handling deferred loading of tools in agent initialization and execution processes.
- Improved the extraction of discovered tools from message history to optimize tool loading behavior.
