Pull request overview

This PR introduces a reusable ReflectionCache facility to reduce repeated reflection lookups across SOFABoot, wires it into key components (health readiness + datasource tracer), and exposes cache stats/clear via a new actuator endpoint.

Changes:

• Add core ReflectionCache implementation with hit/miss statistics and clear support
• Auto-configure the cache via sofa.boot.reflection.cache.enabled and integrate it into readiness health + datasource processing
• Add reflection-cache actuator endpoint plus unit tests and smoke/integration tests
