🐛 fix: Artifacts Type Error, Tool Token Counts, and Agent Chat Import

[danny-avila]

Summary

I fixed issues related to undefined file sizes in the FilePreview component, incorrect token counts for tool calls in context window management, and message import functionality to support the content field.

• Fixed potential undefined size in FilePreview component to prevent runtime errors when size is not defined.
• Handled token counts for tool_call messages in context window management to ensure accurate token calculations in BaseClient.js.
• Updated message import functionality to support the content field, ensuring that messages with content are properly imported.

Change Type

• Bug fix (non-breaking change which fixes an issue)

Testing

I tested these changes by:

• FilePreview Component: Uploaded files with and without the size property to ensure the FilePreview component handles both cases without errors and displays progress correctly.
• Context Window Management: Created conversations involving tool calls and verified that the token counts are calculated correctly without causing context window overflows.
• Message Import Functionality: Imported conversations containing messages with the content field to confirm they are imported properly and display as expected in the chat history.

Test Configuration:

• Environment: Local development environment
• Node.js Version: Specify the version used, e.g., v14.17.0
• Operating System: Specify your OS, e.g., Windows 10 / macOS Catalina / Ubuntu 20.04
