A history expansion followed by a character ineligible for history expansion (e.g. =) isn't highlighted correctly. !!= unquoted is all highlighted as history expansion and "!!=" terminates the history expansion style on the first ! rather than the second.

研究方向
Examine the highlighting rules for history expansion in the zsh syntax highlighting codebase, likely in the 'highlighters' folder. Identify the regex patterns that handle history expansion and adjust them to correctly handle cases like '!!=' (unquoted) and '"!!="' (quoted). Test with appropriate test cases to ensure both scenarios are covered.
