* 🐛 fix: Normalize `output_text` blocks in Responses API input conversion
Treat `output_text` content blocks the same as `input_text` when
converting Responses API input to internal message format. Previously,
assistant messages containing `output_text` blocks fell through to the
default handler, producing `{ type: 'output_text' }` without a `text`
field, which caused downstream provider adapters (e.g. Bedrock) to fail
with "Unsupported content block type: output_text".

* refactor: Remove ChatModelStreamHandler from OpenAI and Responses controllers
Eliminated the ChatModelStreamHandler from both OpenAIChatCompletionController and createResponse functions to streamline event handling. This change simplifies the code by relying on existing handlers for message deltas and reasoning deltas, enhancing maintainability and reducing complexity in the agent's event processing logic.
* feat: Enhance input conversion in Responses API
Updated the `convertInputToMessages` function to handle additional content types, including `input_file` and `refusal` blocks, ensuring they are converted to appropriate message formats. Implemented null filtering for content arrays and default values for missing fields, improving robustness. Added comprehensive unit tests to validate these changes and ensure correct behavior across various input scenarios.
* fix: Forward upstream provider status codes in error responses
Updated error handling in OpenAIChatCompletionController and createResponse functions to forward upstream provider status codes (e.g., Anthropic 400s) instead of masking them as 500. This change improves error reporting by providing more accurate status codes and error types, enhancing the clarity of error responses for clients.

* 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.
* 💻 feat: deeper MCP UI integration in the chat UI using plugins
