Add @available attributes for Logger APIs in BluetoothManager extensions

[Copilot]

Swift compiler errors occur when using Logger and OSLogMessage APIs (macOS 11.0+/iOS 14.0+) without explicit availability annotations.

Changes

• Added @available(macOS 11.0, iOS 14.0, watchOS 7.0, *) to CBCentralManagerDelegate extension (line 197)
• Added @available(macOS 11.0, iOS 14.0, watchOS 7.0, *) to CBPeripheralDelegate extension (line 230)

Both extensions use Logger.main.info() calls throughout their delegate methods, triggering availability errors without these attributes.

@available(macOS 11.0, iOS 14.0, watchOS 7.0, *)
extension BluetoothManager: CBCentralManagerDelegate {
    public func centralManagerDidUpdateState(_ central: CBCentralManager) {
        // ... Logger calls
    }
}

@available(macOS 11.0, iOS 14.0, watchOS 7.0, *)
extension BluetoothManager: CBPeripheralDelegate {
    public func peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: (any Error)?) {
        Logger.main.info("didDiscoverCharacteristicsFor service: \(service)")
        // ... more Logger calls
    }
}

The specified versions align with the project's iOS 14.0 deployment target.

Original prompt

Problem

The Swift build is failing with availability errors because Logger and OSLogMessage APIs require macOS 11.0+ (iOS 14.0+), but the code doesn't have proper @available attributes.

Current Errors

The build fails with errors like:

error: 'Logger' is only available in macOS 11.0 or newer
error: 'OSLogMessage' is only available in macOS 11.0 or newer
error: 'appendInterpolation(_:privacy:)' is only available in macOS 11.0 or newer

These errors occur in Improv-iOS/BluetoothManager.swift in the following extensions:

• extension BluetoothManager: CBCentralManagerDelegate (starting at line 197)
• extension BluetoothManager: CBPeripheralDelegate (starting at line 230)

Solution Required

Add @available attributes to both extensions that use Logger APIs:

For the CBCentralManagerDelegate extension (around line 197):

@available(macOS 11.0, iOS 14.0, watchOS 7.0, *)
extension BluetoothManager: CBCentralManagerDelegate {
    // existing methods...
}

For the CBPeripheralDelegate extension (around line 230):

@available(macOS 11.0, iOS 14.0, watchOS 7.0, *)
extension BluetoothManager: CBPeripheralDelegate {
    // existing methods...
}

Files to Modify

• Improv-iOS/BluetoothManager.swift

Context

The project's deployment target is macOS 12.0 and iOS 15.0, which are both >= the required versions for Logger (macOS 11.0, iOS 14.0). Adding these availability attributes satisfies the Swift compiler's requirements while maintaining compatibility with the project's deployment targets.
