Rule Implementations Package

This package contains all rule implementation modules.

Naming Convention:
- Module name: snake_case matching the rule type name
  Example: window_setback.py for type 'window_setback@1.0'
  
- Class name: PascalCase + 'Rule' suffix
  Example: WindowSetbackRule
  
The rule engine uses load_rule() from rule_interface to dynamically
import modules from this package based on the 'type' field in rules.yaml.
