Pulse 4.2.6

What's Changed

• Disable Swift 6 compatibility in Swift package to ensure Pulse compiles if added as a dependency under Xcode 16 by @NachoSoto in #264
• Fix some of the Swift 6 errors (more work is needed and will be done in the upcoming versions)
• Move Identifiable conformances to Pulse to remove the "retroactive" conformance warnings in Swift 6
