* fix: Update parseTextParts to handle undefined content parts
- Modified the parseTextParts function to accept an array of content parts that may include undefined values.
- Implemented optional chaining to safely check for the type of each part, preventing potential runtime errors when accessing properties of undefined elements.
* refactor: Tool Call Configuration with Session Context
- Added support for including session ID and injected files in the tool call configuration when a code session context is present.
- Improved handling of tool call configurations to accommodate additional context data, enhancing the functionality of the tool execution handler.
* chore: Update @librechat/agents to version 3.1.37 in package.json and package-lock.json
* test: Add unit tests for createToolExecuteHandler
- Introduced a new test suite for the createToolExecuteHandler function, validating the handling of session context in tool calls.
- Added tests to ensure correct passing of session IDs and injected files based on the presence of codeSessionContext.
- Included scenarios for handling multiple tool calls and ensuring non-code execution tools are unaffected by session context.
* test: Update createToolExecuteHandler tests for session context handling
- Renamed test to clarify that it checks for the absence of session context in non-code-execution tools.
- Updated assertions to ensure that session_id and _injected_files are undefined when non-code-execution tools are invoked, enhancing test accuracy.
