This pull request introduces several improvements and bug fixes to the AI integration logic in js/owrap.ai.js, as well as a minor fix in js/openaf.js. The changes mainly enhance the handling of model metadata, token usage statistics, prompt formatting, and function call responses, while also improving error handling and resource cleanup.

AI integration improvements:

• Enhanced metadata extraction for Gemini responses, including support for modelVersion, responseId, and additional token usage fields such as cachedContentTokenCount and thoughtsTokenCount in the stats object.
• Improved filtering and formatting of prompts and conversation history, ensuring only defined entries are processed and system instructions are correctly constructed from both parts and content fields. [1] [2] [3]
• Refined handling of function call responses: now parses JSON results when possible, wraps results in consistent structures (result, items), and ensures the response content is always an object.
• Fixed a bug where tool functions were incorrectly passed to recursive prompt calls, now passing an empty array as intended.

Resource management and error handling:

• In js/openaf.js, added a check to ensure ojob is defined before attempting to delete its daemon property, and improved temporary file cleanup by always removing the temp file after loading jobs, even if an error occurs.
