* Refactor rules to utilize callListRule base structure - Introduced a new base structure `callListRule` in `rules/base.go` to standardize the implementation of rules that check for specific function calls. - Updated existing rules to inherit from `callListRule`, simplifying their structure and removing redundant ID methods. - Modified the `MetaData` field to use `RuleID` instead of `ID` for consistency across rules. - Removed the `weakcryptohash.go` and `weakdepricatedcryptohash.go` files as their functionality has been integrated into the new structure. * fix(tlsconfig): correct MetaData field name in generated TLS check * refactor: standardize rule metadata and call list initialization
