Pull request overview

This PR refactors selector/rule matching in AbstractShenyuPlugin to properly leverage the existing two-level match cache (L1 WindowTinyLFU + L2 matching strategy), and adds targeted tests to cover L1 cache-hit behavior.

Changes:

• Fix selector/rule execution flow to return immediately on L1 cache hits (including cached negative-match sentinels).
• Refactor match-caching logic via a shared cacheMatchData(...) helper and minor hot-path optimizations in matching.
• Add unit tests validating L1 cache-hit and negative-sentinel short-circuit behavior for both selector and rule matching.
