Pull Request Overview

This PR aims to reduce route dispatch allocations by refactoring the router’s handler slice allocation and adding a benchmark to test the performance of matchAndDispatch.

• Added Benchmark_MatchAndDispatch in unit_router_test.go
• Moved the declaration of the handlers slice outside the message processing loop in router.go
• Cleared the handlers slice in each loop iteration to reuse allocated memory
