feat: added /export comment to export self-contained HTML file built from webui

[ErikBjare]

Replaces #105

Closes #32

Re-uses the web UI so that we maximize code reuse

In the future, we should also embed images/media from the conversation. Possibly by base64 encoding (downscaled?) versions into messages.

Important

Adds /export command to export chat logs as standalone HTML files, with updates to handle embedded data in JavaScript.

• Feature:
  • Adds /export command in commands.py to export chat logs as standalone HTML files using export_chat_to_html().
  • New export.py module for exporting chat logs to HTML, embedding chat data and styles directly into the HTML.
• JavaScript:
  • Updates main.js to check for window.CHAT_DATA and handle embedded chat data for exported HTML files.
  • Modifies mdToHtml() in main.js to unescape HTML entities before processing markdown.

  The replace_or_fail function is a good practice to ensure that the HTML structure is as expected. However, ensure that the error message provides enough context for debugging.
• Reason this comment was not posted:
  Confidence changes required: 50%
  The replace_or_fail function is used to ensure that specific HTML elements are replaced in the template. However, if the template changes and the expected elements are not found, this will raise an error. This is a good practice to ensure that the HTML structure is as expected.

2. gptme/commands.py:152

• Draft comment:
  Ensure that manager.undo(1, quiet=True) is necessary for the /export command. It might not be needed if the command itself doesn't alter the log in a way that needs undoing.
• Reason this comment was not posted:
  Confidence changes required: 50%
  The handle_cmd function uses manager.undo(1, quiet=True) before executing commands. This is likely intended to undo the command itself from the log, but it might not be necessary for all commands.

Consider using DOMPurify.sanitize to sanitize HTML content before rendering to prevent XSS vulnerabilities.
