Zero-Allocation Context Pooling

To maximize throughput and eliminate Garbage Collection (GC) pauses under high concurrency, Volten implements Context Pooling:

• A pool of RequestContext objects is pre-allocated upon server startup.
• When an incoming request arrives, an idle context is retrieved from the pool.
• Once the response completes, ctx.reset() clears all request-specific fields, headers, and ctx.state, returning the context back to the pool.
• Result: Zero object allocations per request for the context lifecycle.
