Add Support for Mathematical Minus Character in Queries

Why it matters

This feature improves query parsing by allowing the use of the true mathematical minus symbol −, which visually differs from the hyphen-minus, thereby increasing readability and compatibility with queries copied from mathematical texts or editors.

How to use it

Users can freely use the mathematical minus character − in their queries wherever the standard minus operator - is valid. No additional configuration is needed; the parser automatically recognizes and treats − as a minus operator.
