Subject: feat(search): add tag: alias for # and ! alias for negation (#2425)

Add `tag:` as an alternative syntax to `#` for tag search queries,
and `!` as an alternative to `-` for negating qualifiers. This provides
more intuitive syntax options for users who prefer text-based qualifiers
over special characters.
