v1.1.0

Concurrency Fixes

• PoolChatConfiguration — Mutable statics (logger, rejectUnencryptedMessages, enableHistorySync) are now protected by NSLock (were unguarded data races)
• VoiceRecordingService — Removed unnecessary Task { @MainActor in } wrappers from timer closures (already on main thread; was creating 10 Task allocations/sec)
• PoolChatViewModel — Setup Tasks are now tracked in an array, cancelled on re-entry and terminate() to prevent racing duplicate tasks on reconnect; added Task.isCancelled checks for cooperative cancellation
