Force output URLs to use existing files if local

[Josh-XT]

Fixes #1412

This pull request introduces a significant enhancement to the run method in the agixt/Interactions.py file. The main change is the addition of a mechanism to handle broken file references in the response by searching for and replacing them with the most similar or recently modified files in the directory.

Enhancements to file reference handling:

• Added logic to detect broken file references in the response and attempt to replace them with the most similar or recently modified files in the working directory.
• Implemented a similarity check using SequenceMatcher to find the best matching file when the exact file is not found.
• Added a fallback mechanism to prefer recently created files (within the last 5 minutes) over similar names if available.
• Updated the response to replace broken links with the found files and logged the replacements for traceability.
