v1.1.0

Concurrency Fixes

• ConnectionPoolConfiguration — Logger access is now protected by NSLock (was an unguarded nonisolated(unsafe) mutable global)
• MeshTopology — Removed TOCTOU-prone computed property wrappers that acquired the lock twice on read-modify-write
• Peer — Replaced static var cache with static let closure for thread-safe one-time initialization
• ConnectionPoolManager — Delayed Tasks are now tracked and cancelled on disconnect, preventing stale operations on rapid reconnect cycles
• UncheckedSendableBox — Added safety documentation
