What

The --tools flag's parsing and validation logic, which resolves entries like !Bash into deny rules, now references a single named constant for the "!" negation prefix, used both in the parsing logic itself and in the warning/error messages about unmatched or malformed tool entries.

Why

This is an internal cleanup with no described change in how --tools behaves for users.
