Changelog Entry

Description

This change updates the tag_content_handler to correctly detect and escape literal closing tags like </think>. Previously the parser treated </think> as part of the reasoning block, causing all subsequent assistant output to be swallowed inside the “thinking” section. Now the closing tag is recognized and content after it is rendered normally.

Key Changes

Changed

Improved regex logic in to match and escape closing tags.

Fixed

[List any fixes, corrections, or bug fixes]

Breaking Changes

BREAKING CHANGE: Didn't tested for others llms providers
