Spring Boot	PythonBoot
@SpringBootApplication	@pythonboot_application + PythonBootApplication
@Component / @Service / @Configuration / @Bean	matching lowercase decorators
@Autowired / @Qualifier / @Primary	typed constructor / autowired() / qualifier / primary=True
@RestController and mappings	@controller and HTTP decorators
@ControllerAdvice	@controller_advise
@Aspect / advice	@aspect / advice decorators
@Transactional	@transactional
@ConfigurationProperties / conditions	matching PythonBoot decorators

FastAPI remains PythonBoot's HTTP, validation, and OpenAPI layer. Bean self-invocation does not cross the AOP proxy.
