/**
 * Placeholder plugin for general method reuse detection
 * 
 * This is a placeholder implementation for the METHOD_REUSE_CLEANUP constant.
 * It corresponds to general method reuse detection functionality that is planned
 * for future implementation.
 * 
 * The METHOD_REUSE_CLEANUP constant is already used in the UI preferences but
 * does not yet trigger any cleanup operations. This placeholder allows the enum
 * structure to match the constant without implementing the full functionality.
 * 
 * Compare with InlineSequencesPlugin which provides the complete implementation
 * for METHOD_REUSE_INLINE_SEQUENCES constant.
 * 
 * Future implementation should detect similar methods across the codebase and
 * suggest refactoring opportunities. See MethodReuseFinder for planned functionality.
