Pull request overview

This pull request refactors how directives are represented and accessed throughout the codebase. The key change is moving from treating directives as StringLiteral[] to treating them as TSESTreeDirective[] (directive expression statements), which aligns better with the ESTree/TSESTree specification where directives are expression statements with a directive property.

Changes:

• Introduced TSESTreeDirective and TSESTreeDirectiveLike types to represent directive expression statements
• Updated isDirective to check for the directive property on expression statements rather than checking if expressions are string literals
• Modified getFileDirectives and getFunctionDirectives to return directive expression statements instead of string literals
• Updated semantic node interfaces (SemanticFunc, FunctionComponentSemanticNode, etc.) to use the new directive type
• Updated ESLint plugin rules and component collector to access directive values via d.expression.value
• Updated documentation files to reflect the new directive type
