🆔 fix: Atomic File Dedupe, Bedrock Tokens Fix, and Allowed MIME Types (#11675)
* feat: Add support for Apache Parquet MIME types

- Introduced 'application/x-parquet' to the full MIME types list and code interpreter MIME types list.
- Updated application MIME types regex to include 'x-parquet' and 'vnd.apache.parquet'.
- Added mapping for '.parquet' files to 'application/x-parquet' in code type mapping, enhancing file format support.

* feat: Implement atomic file claiming for code execution outputs

- Added a new `claimCodeFile` function to atomically claim a file_id for code execution outputs, preventing duplicates by using a compound key of filename and conversationId.
- Updated `processCodeOutput` to utilize the new claiming mechanism, ensuring that concurrent calls for the same filename converge on a single record.
- Refactored related tests to validate the new atomic claiming behavior and its impact on file usage tracking and versioning.

* fix: Update image file handling to use cache-busting filepath

- Modified the `processCodeOutput` function to generate a cache-busting filepath for updated image files, improving browser caching behavior.
- Adjusted related tests to reflect the change from versioned filenames to cache-busted filepaths, ensuring accurate validation of image updates.

* fix: Update step handler to prevent undefined content for non-tool call types

- Modified the condition in useStepHandler to ensure that undefined content is only assigned for specific content types, enhancing the robustness of content handling.

* fix: Update bedrockOutputParser to handle maxTokens for adaptive models

- Modified the bedrockOutputParser logic to ensure that maxTokens is not set for adaptive models when neither maxTokens nor maxOutputTokens are provided, improving the handling of adaptive thinking configurations.
- Updated related tests to reflect these changes, ensuring accurate validation of the output for adaptive models.

* chore: Update @librechat/agents to version 3.1.38 in package.json and package-lock.json

* fix: Enhance file claiming and error handling in code processing

- Updated the `processCodeOutput` function to use a consistent file ID for claiming files, preventing duplicates and improving concurrency handling.
- Refactored the `createFileMethods` to include error handling for failed file claims, ensuring robust behavior when claiming files for conversations.
- These changes enhance the reliability of file management in the application.

* fix: Update adaptive thinking test for Opus 4.6 model

- Modified the test for configuring adaptive thinking to reflect that no default maxTokens should be set for the Opus 4.6 model.
- Updated assertions to ensure that maxTokens is undefined, aligning with the expected behavior for adaptive models.
