⏲️ feat: Defer Loading MCP Tools (#11270)

* WIP: code ptc

* refactor: tool classification and calling logic

* 🔧 fix: Update @librechat/agents dependency to version 3.0.68

* chore: import order and correct renamed tool name for tool search

* refactor: streamline tool classification logic for local and programmatic tools

* feat: add per-tool configuration options for agents, including deferred loading and allowed callers

- Introduced `tool_options` in agent forms to manage tool behavior.
- Updated tool classification logic to prioritize agent-level configurations.
- Enhanced UI components to support tool deferral functionality.
- Added localization strings for new tool options and actions.

* feat: enhance agent schema with per-tool options for configuration

- Added `tool_options` schema to support per-tool configurations, including `defer_loading` and `allowed_callers`.
- Updated agent data model to incorporate new tool options, ensuring flexibility in tool behavior management.
- Modified type definitions to reflect the new `tool_options` structure for agents.

* feat: add tool_options parameter to loadTools and initializeAgent for enhanced agent configuration

* 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.

* chore: update @librechat/agents dependency to version 3.0.72

* chore: update @librechat/agents dependency to version 3.0.75

* refactor: simplify tool defer loading logic in MCPTool component

- Removed local state management for deferred tools, relying on form state instead.
- Updated related functions to directly use form values for checking and toggling defer loading.
- Cleaned up code by eliminating unnecessary optimistic updates and local state dependencies.

* chore: remove deprecated localization strings for tool deferral in translation.json

- Eliminated unused strings related to deferred loading descriptions in the English translation file.
- Streamlined localization to reflect recent changes in tool loading logic.

* refactor: improve tool defer loading handling in MCPTool component

- Enhanced the logic for managing deferred loading of tools by simplifying the update process for tool options.
- Ensured that the state reflects the correct loading behavior based on the new deferred loading conditions.
- Cleaned up the code to remove unnecessary complexity in handling tool options.

* refactor: update agent mocks in callbacks test to use actual implementations

- Modified the agent mocks in the callbacks test to include actual implementations from the @librechat/agents module.
- This change enhances the accuracy of the tests by ensuring they reflect the real behavior of the agent functions.
