feat(ipuaro): add decorator extraction to initial context

Extract decorators from classes and methods for NestJS/Angular support.
Decorators are now shown in initial context:
- @Controller('users') class UserController
- @Get(':id') async getUser(id: string): Promise<User>

Changes:
- Add decorators field to FunctionInfo, MethodInfo, ClassInfo
- Update ASTParser to extract decorators from tree-sitter nodes
- Update formatFileSummary to display decorators prefix
- Add 18 unit tests for decorator extraction and formatting
