⚡ Bolt: Optimize case-insensitive routing comparisons

Browse source 
Replaced allocation-heavy strings.ToLower() == strings.ToLower() checks
with zero-allocation strings.EqualFold() in pkg/routing/route.go.

What: Replace `strings.ToLower(a) == strings.ToLower(b)` with `strings.EqualFold(a, b)` in `ResolveRoute` bindings checks.
Why: `ResolveRoute` is an extremely hot path evaluated for every single incoming message across the system. Calling `strings.ToLower()` allocates new strings on the heap and creates unnecessary GC pressure for case-insensitive checks.
Impact: Reduces memory allocations during feature routing bounds checking from O(N) to O(1) by performing zero-allocation case-insensitive evaluations.
Measurement: Compare memory allocations and CPU profiling in `ResolveRoute` or run benchmark tests checking routing rules.
