v1.1.2

Performance improvements

• RPITIT handler dispatch — Handler trait switched to return-position impl trait, eliminating double Box::pin allocation per request (1 heap alloc instead of 2)
• Lock-free route config — RwLock<Option<Duration>> and RwLock<Option<SimdJsonMode>> replaced with OnceLock for zero-overhead reads on the hot path
• Static router reference — Router is leaked into &'static to eliminate all Arc refcount bumps per connection and per request
• Middleware emptiness flags — AtomicBool flags on Router and Route skip ArcSwap::load() when no middleware is registered
• HTTP/1.1 pipeline flush — Enabled pipeline_flush(true) on the hyper HTTP/1 builder for better pipelining throughput
• Method clone eliminated — req.method().clone() removed from dispatch hot path, using direct reference instead
• Inline dispatch — #[inline] added to the dispatch function
